As a critical material in fields such as aerospace, integrated circuits, and high-speed rail transportation, high-end copper alloys have an increasingly prominent strategic position. Despite China's copper semis production and consumption ranking first globally for consecutive years, with a self-sufficiency rate of general copper semis reaching as high as 96%, the country still heavily relies on imports for high-end copper alloy products. To address this "chokehold" challenge, SMM recently launched an initiative for industrial resource integration, collaborating with upstream and downstream enterprises in the industry chain, as well as research institutions, to meticulously produce the "2026 China Copper Alloy Materials Sourcing Guide" , aiming to advance the localisation process of high-end copper alloy materials and facilitate the transition from being a "major material producer" to a "leading material powerhouse." This time, CNMC Zhengrui (Shandong) Copper Industry Co., Ltd. actively participated in the joint production of the sourcing guide as a partner, jointly promoting the healthy and rapid upgrading of China's copper alloy materials industry chain. CNMC Zhengrui (Shandong) Copper Industry Co., Ltd. , affiliated with China Nonferrous Metal Mining (Group) Co., Ltd., is the only enterprise in China with full-chain production capabilities, including processing of base materials for copper foil, high-precision copper foil rolling, surface anti-oxidation, reddening, and blackening treatments. It is the largest high-precision copper alloy plate, strip, and high-precision rolled copper foil production site in Shandong Province, renowned domestically, and welcomes cooperation discussions. Main Products: Copper and copper alloy plates, strips, and sheets (red copper, cupronickel, brass, iron bronze, copper-nickel-silicon, copper-nickel-tin, etc.); Copper and copper alloy rolled foil materials (high-flexibility copper foil, blackened foil, reddened foil, anti-oxidation bare foil, alloy foil, etc.) Contact Information Gao Ming Director of Sales Department 138 6954 2345 Click here to receive a free copy of the "2026 China Copper Alloy Materials Sourcing Guide" SMM Contact Person Zhang Wencheng 187 6645 7954 zhangwencheng@smm.cn

On April 23, at the CCIE 2025 SMM (20th) Copper Industry Conference & Copper Industry Expo - Main Forum, hosted by SMM Information & Technology Co., Ltd., Tong Qingping, Chief Scientist and PhD of China Nonferrous Metal Mining (Group) Co., Ltd., analyzed the current development status and high-quality development trends of China's copper processing industry.

On April 17, at the AICE 2025 SMM (20th) Aluminum Industry Conference and Aluminum Industry Expo - Main Forum, jointly organized by SMM Information & Technology Co., Ltd., SMM Metal Trading Center, and Shandong Aisi Information Technology Co., Ltd., and co-organized by Zhongyifeng Jinyi (Suzhou) Technology Co., Ltd. and Lezhi County Qianrun Investment Service Co., Ltd., Mo Xinda, Director of the Light Metals Department of the China Nonferrous Metals Industry Association and Deputy Secretary General of the Aluminum Branch, shared the theme "In-depth Analysis of China's Aluminum Processing Industry: Hot Topics and Future Development Trends." ► Bauxite Guinea exported 146 million mt of bauxite in 2024, with China importing 110 million mt from Guinea, accounting for 70% of total imports. He also analyzed the average import unit price of bauxite and the price trend of alumina. ► Aluminum Supply-side structural reform + large-scale transformation + green transformation ► Secondary Aluminum Secondary aluminum continues to increase. In 2024, secondary aluminum production reached 10.55 million mt, up 8.9% YoY. Secondary aluminum is shifting towards applications in wrought aluminum alloys. With the integration of secondary aluminum and aluminum processing, it is expected that by 2025, the usage of secondary aluminum in the field of wrought aluminum alloys will exceed 50%. Secondary aluminum is transitioning towards grade preservation and closed-loop recycling. ► Overseas Investment • Full industry chain layout • Proactive and passive actions • Concentrated investment • High popularity remains ► I. Overview of the Processing Industry China's aluminum processing equipment level is internationally leading, with a complete range of products. • Significant late-mover advantage in equipment. Extrusion (over 300 imported), hot rolling (over 200 lines), cast rolling (about 1,000 units), continuous casting and rolling (2 lines), foil rolling (over 600 units), covering internationally renowned brands such as UBE, SMS, Minox, Danieli, Voestalpine, and Aschenbach. • Domestic equipment manufacturing capabilities have significantly improved. Achieving import substitution while exporting in bulk. China's aluminum processing layout is based domestically, with consideration for overseas, showing a significant trend towards globalization. II. Situation Observation - Foreign Trade Aluminum is an important trade surplus product among non-ferrous metals. In 2024, the export volume of aluminum semis and products hit a record high, with total overseas consumption exceeding 10 million mt. He introduced that the export market for aluminum semis and products is relatively dispersed. Trade friction is a byproduct of increased export competitiveness. ► The foreign trade situation is severe, and trade friction has become the norm. • Numerous: Uninterrupted and more frequent (over 80 cases). • Various types: Conventional practices are more frequent: anti-dumping, anti-subsidy, double anti, anti-circumvention, US 301, 232; New methods are emerging: US Xinjiang-related Act, EU Carbon Border Adjustment Mechanism, EU Circular Economy Action Plan, etc. • Wide regions, most intensive in the US and Europe: US, Europe, Canada, Australia (ongoing); Southeast Asia (heating up); South America, Eurasia, GCC (increasing). • Complex situation: Bilateral to multilateral; traditional markets to emerging markets; economic to pan-political; continuously enriched toolbox (design, standards, equipment, enterprises). He indicated that there are still many uncertain factors... II. Situation Observation - Carbon Constraints ► EU Carbon Border Adjustment Mechanism (CBAM) Timetable: • October 2023 - the end of 2025: Transition period • 2026: Start of carbon fee collection - carbon fees are paid by EU importers Products involved: Aluminum in CBAM includes unwrought aluminum, aluminum semis, and some aluminum products. CBAM influencing factors: CBAM = (Actual carbon content of exported products - Free quota of EU products) X (EU carbon price - Export country carbon price). II. Situation Observation - Carbon Constraints We judge that CBAM will have no impact in the short term, and limited direct impact in the long term: • Currently only includes direct emissions, and the direct emission levels of various countries are not significantly different • If indirect emissions are not taxed, there is no difference in CBAM carbon fee accounting between using thermal power aluminum and green power aluminum • Using secondary aluminum raw materials can significantly reduce carbon emissions (secondary = 3-5% of primary) • The EU market futures are relatively limited UK version of CBAM: Time: 2027, Scope: Direct emissions + indirect emissions. ► Aluminum is about to be included in the national carbon emission trading unified market According to the work arrangement of the Ministry of Ecology and Environment, the aluminum industry is about to be included in the national carbon emission trading market management. • Regarding the coverage of greenhouse gases, the controlled gases in the aluminum industry are carbon dioxide, carbon tetrafluoride, and hexafluoroethane; • Regarding the scope of carbon emissions, only greenhouse gas emissions directly generated by the use of fossil fuels are traded, including carbon emissions from anode consumption and anode effects; • Regarding quota allocation, the number of free quotas obtained by enterprises is linked to product production (output). • We judge that the net consumption of carbon anodes will be the core factor affecting the surplus or shortage of carbon trading quotas for aluminum enterprises. Improving the quality of carbon anodes is crucial and imperative. ► End-users' independent carbon reduction cannot be separated from material support He cited cases of carbon reduction by BMW, Apple, and Tetra Pak China. III. Several Views 1. Professional development will be the focus of building comparative advantages in China's aluminum processing. • Largest, strongest, but also the most difficult (competition, "tariff war", cancellation of export tax rebates); • Investment needs to be rational!!! Development momentum should be based on market demand, not just on becoming a large enterprise or based on government demand; • Future development should not pursue being large and comprehensive, but should be based on specialization and refinement; • Attention should be paid to cultivating new quality productive forces (emphasis on technology, products, and applications); • Persistently expand applications (substitution and anti-substitution, seeking increments). 2. Improving the ability and spirit of struggle is crucial to fully consolidating the export market. • Fully utilize the four-body linkage mechanism to fully respond to trade friction • Diversify export countries • Extend the industry chain to improve the competitiveness of export products • Go global? • China's aluminum consumption needs overseas markets, and global aluminum consumption cannot do without Chinese products! 3. Attach great importance to green development and strive to build future competitive highlands. • Continuously enrich the green development toolbox, and incorporate green and low-carbon work into the governance system of industry enterprises Ø Improve energy efficiency (technical equipment transformation and upgrading, application of graphitized cathodes, etc.) Ø Green power aluminum (25.2%; market transactions, self-built, generation-grid-load-storage) Ø Secondary aluminum (production of 10.55 million mt; grade preservation recycling is more important) Ø Carbon trading (production/electricity consumption; strive to sell quotas) Ø Domestic sales/export (do a good job in resource allocation) Ø CCER (has been restarted) Ø Financial derivatives (integration of industry and finance) Ø ...... 》Click to view the special report on AICE 2025 SMM (20th) Aluminum Industry Conference and Aluminum Industry Expo

On April 16, at the AICE 2025 SMM (20th) Aluminum Industry Conference and Aluminum Industry Expo—Aluminum Casting Technology Forum, co-hosted by SMM Information & Technology Co., Ltd., SMM Metal Trading Center, and Shandong Aisi Information Technology Co., Ltd., and co-organized by Zhongyifeng Jinyi (Suzhou) Technology Co., Ltd. and Lezhi County Qianrun Investment Service Co., Ltd., He Xiangwen, Chief Engineer of the Process Department at China Nonferrous Metals Processing Technology Co., Ltd., discussed the innovation and application of short-process aluminum processing technology. 01 Overview of Short-Process Aluminum Processing Technology 1.1 Overview of Short-Process Aluminum Processing Technology Definition of Short-Process Technology: Short-process technology refers to the process of directly producing the desired product from liquid aluminum, omitting some intermediate steps in traditional processes, such as directly casting and rolling liquid aluminum into thin sheets, reducing energy consumption and production time. This process features a short flow, low energy consumption, and high production efficiency, meeting the modern aluminum processing industry's demands for efficiency, energy savings, and environmental protection. Advantages of Short-Process Technology: Energy Consumption Reduction: In traditional aluminum processing, liquid aluminum undergoes multiple cooling and reheating steps, resulting in high energy consumption. Short-process technology eliminates these steps, directly producing products from liquid aluminum, significantly reducing energy consumption. Production Efficiency Improvement: By omitting intermediate steps, the production cycle is shortened, and production efficiency is improved, enabling faster response to market demands. Current Application Status of Short-Process Technology: Currently, the application of short-process technology in the aluminum processing industry is gradually increasing, particularly in the production of thin sheets, strips, and other products, where it shows significant advantages. For example, some companies use short-process technology to produce automotive aluminum sheets, foils, and general 1-series, 3-series, and 8-series aluminum sheets, not only improving production efficiency but also reducing costs. This discussion focuses on the production of plate and strip materials, as their production process is generally the longest, most energy-intensive, and requires the highest investment in aluminum processing. 1.1 Main Short-Process Aluminum Processing Technologies Twin-Roll Casting Process, Micromill Continuous Casting and Rolling Process, Hazelett Continuous Casting and Rolling Process 1.2 Main Equipment for Short-Process Technology 02 Innovation and Development of Twin-Roll Casting Process 2.1 Typical Casting and Rolling Production Line Twin-Roll Caster: The twin-roll solidifies liquid aluminum into cast-rolled strips, with common strip thicknesses ranging from 5-12mm (fast cast-rolled strip thicknesses range from 3-8mm), and common alloy series include 1XXX, 3XXX, 8XXX, and some 5XXX. 2.1 Main Configuration of Casting and Rolling Production Line Note: The above configuration omits auxiliary facilities such as electromagnetic stirring devices, online treatment devices, dust removal, and furnace-side degassing devices. 2.2 Main Layout Methods of Casting and Rolling Production Line Mirror Layout of Adjacent Casters: Advantages: Adjacent casting lines can be managed by one team, reducing the number of personnel. Same-Direction Layout of Adjacent Casters: Advantages: Caster equipment components can be shared, reducing the number of spare parts. 2.3 Classification of Melting Furnaces/Holding Furnaces 2.4 Innovative Technologies in Casting and Rolling Process ►Innovation in Caster Roll Technology: The application of new caster roll materials and surface treatment technologies has improved the service life of caster rolls and the quality of cast-rolled coils. For example, caster rolls made of nano-composite materials or copper roll sleeves have higher thermal conductivity and wear resistance. ►Innovation in Casting and Rolling Process Control Technology: The application of automated control systems in the casting and rolling process has achieved precise control over the process. Through sensors and computer technology, parameters such as liquid aluminum temperature, composition, and caster roll speed are monitored in real-time and automatically adjusted to ensure stable quality of cast-rolled coils. ►Innovation in Liquid Aluminum Purification Technology: Advanced liquid aluminum purification technologies, such as electromagnetic stirring, ultrasonic treatment, and fine filtration, effectively remove impurities and gases from liquid aluminum, improving the purity of cast-rolled coils and altering their grain size. The application of these technologies has significantly enhanced the mechanical properties and surface quality of cast-rolled coils. 2.5 Optimization and Improvement of Casting and Rolling Process ►Intelligent Development of Casting and Rolling Process: Intelligent technologies will be more widely applied in the casting and rolling process. Through artificial intelligence and big data technologies, intelligent control and optimization of the casting and rolling process will be achieved. ►Development of High-Precision Casting and Rolling Process: With increasing market demands, high-precision casting and rolling processes will become a future trend. By further optimizing process parameters and equipment technology, thinner and more uniform cast-rolled coils will be produced. Adding a roll gap adjustment system for automatic roll gap adjustment before casting and rolling. Depending on the alloy grade, adding edge milling functionality to reduce large-area cracking of cast-rolled strips. ►Green Development of Casting and Rolling Process: Green development is an inevitable choice for the casting and rolling process. More environmentally friendly production processes and equipment will be adopted to reduce energy consumption and environmental pollution, such as using gas refining instead of solid particle refining agents. 03 Innovation and Development of Continuous Casting and Rolling Process 3.1 Micromill Continuous Casting and Rolling Process Configuration •Micromill technology combines casting and rolling into one process, using twin-roll high-speed cooling during casting. High-speed casting and rolling are performed horizontally, solving the central segregation issue and production speed limitations of traditional casting and rolling technologies. •Micromill has a faster production speed, requiring timely and sufficient liquid aluminum supply for the casting section. Therefore, the furnace is generally larger and has at least two interchangeable units, preferably using liquid aluminum as the main raw material. The throughput of online degassing and filtration is also correspondingly larger, generally matching the liquid aluminum supply. 3.1 Overview of Micromill Continuous Casting and Rolling Process •Alcoa officially announced the commercial production of Micromill technology by the end of 2015. Currently, there are only two pilot lines, located at the San Antonio and Reno plants. •This technology is suitable for producing 5XXX and 6XXX series alloys. The cast product width can exceed 1,700mm, with thickness generally ranging from 2-7mm, casting speed from 27-61 m/min, and cast billet temperature at 567℃, which can be further rolled into 1-4mm thin sheets by a continuous rolling mill (San Antonio plant data). •The main product is the blank for automotive inner and outer panels, with the biggest advantage being the ability to replace automotive panels currently produced by hot rolling. 3.1 Characteristics of Micromill Continuous Casting and Rolling Process •Short Process Flow: Traditional hot rolling of slabs takes about 20 days to convert aluminum melt into coils, while Micromill completes this in just 20 minutes. •Small Footprint, Low Energy Consumption: The footprint is 1/4 of traditional hot rolling lines, and energy consumption is 1/2. •Superior Product Performance: High solidification speed greatly improves the microstructure, resulting in fine grains. Formability is 40% higher and strength is 30% higher than traditional automotive aluminum sheets, providing greater design flexibility and better vehicle performance for customers. 3.2 Hazelett Continuous Casting and Rolling Process Configuration •Hazelett continuous casting and rolling technology consists of continuous casting and rolling, with the core being continuous casting. During casting, aluminum melt enters a mold cavity formed by two fully tensioned steel belts and two rectangular metal block chains that can move according to width requirements. The steel belts and metal block chains move simultaneously, and cooling water indirectly cools the steel belts to solidify the melt in the mold cavity, completing the casting. •Hazelett continuous casting and rolling has a higher hourly production capacity than Micromill, requiring more timely and sufficient liquid aluminum supply for the casting section. Therefore, the furnace is generally larger and has at least 3-4 interchangeable units, preferably using liquid aluminum as the main raw material. The throughput of online degassing and filtration is also correspondingly larger, generally matching the liquid aluminum supply. 3.2 Overview of Hazelett Continuous Casting and Rolling Process •Domestically, Longding Aluminum in Luoyang, Henan (commissioned in 2012) and Liansheng Light Alloy in Inner Mongolia (commissioned in 2016) each introduced one Hazelett aluminum plate and strip production line. •This method has a fast casting speed and is matched with subsequent rolling mills. The main products are aluminum foil rolling blanks and general 1XXX, 3XXX, 8XXX, and some 4XXX, 5XXX, 6XXX series products. The cast product thickness generally ranges from 16-50mm, with a casting speed of 3-8 m/min, which can be further rolled into thin sheets with thicknesses of 1.0-7.0mm and widths of 1,300-1,935mm. •The main products that can be produced include packaging foil, cable strips, container foil, and air-conditioner foil. 3.2 Characteristics of Hazelett Continuous Casting and Rolling Process •Fully enclosed liquid aluminum feed pool, maintaining natural and stable liquid aluminum flow. •The feed nozzle tip is made of special ceramic material with good thermal stability, allowing gases released from the liquid aluminum to permeate through the nozzle tip. •Steel belts have good stability and are preheated to 150℃ by induction. •High-strength magnetic support rolls are used to suppress local thermal deformation. •Special coatings are applied to the contact surface between the cast billet and the continuously moving, water-cooled steel belts. •Inert gas is injected into the mold cavity through the upper and lower parts of the nozzle tip, allowing adjustment of the steel belt cooling rate as needed. 3.3 Other Continuous Casting and Rolling Processes 1. Kaiser Micro Twin-Belt Continuous Casting and Rolling Machine •An advancement on the Hazelett continuous casting and rolling line, initially intended for specialized production of can body stock. •However, the stability and uniformity of its can stock quality are far inferior to hot-rolled blanks, so it has not been widely adopted. 2. Launa Method (Caster II) Continuous Casting and Rolling Machine •The casting principle is essentially the same as the Hazelett continuous casting and rolling line, with the difference being that the upper and lower surfaces of the mold cavity are not steel belts but chill blocks moving in the same direction. •Mainly used for producing hot-rolled coils for cold-rolled aluminum foil strips, it is also unstable in can stock strip blanks, so it has no fundamental difference compared to Hazelett continuous casting and rolling. 3. MAN Continuous Casting and Rolling Machine (UK) •Liquid aluminum enters the mold cavity formed by a steel belt and a mold groove ring mounted on a crystallization wheel. Heat is removed by the steel belt and mold groove ring, solidifying the aluminum, which is then exported from the outlet as the crystallization wheel rotates, entering subsequent rolling mills. •The product width of such production lines is generally no more than 500mm, with a thickness of about 20mm, and the hot-rolled coils are 2.5mm thick for cold rolling, limiting its adoption. 3.4 Innovation in Continuous Casting and Rolling Process Innovation in Casting Technology: Different casting technologies are adopted by optimizing nozzle structure, cooling cavity structure, and casting parameters to improve casting quality and production efficiency. For example, new nozzle materials and structures are used to allow more uniform flow of liquid aluminum into the casting mold area; different forms of cooling cavities are used to enhance the cooling capacity of continuous casting. Innovation in Rolling Technology: Advanced rolling technology is adopted to improve the quality of strips by optimizing the structure of rolling mills and rolling parameters. For example, multi-stand tandem hot rolling mills and cold rolling mills are used to precisely control the thickness and surface quality of strips. Innovation in Automation Control Technology: Highly automated control systems are employed to monitor and control various parameters in the casting and rolling processes in real-time through sensors and computer technology. For instance, the Automatic Gauge Control (AGC) and Automatic Flatness Control (AFC) systems are used to precisely control the thickness and flatness of strips. Innovation in Cooling Technology: Advanced cooling technology is utilized to enhance cooling efficiency by optimizing the structure and parameters of the cooling system. For example, multi-point cooling technology is applied to ensure uniform cooling of strips at different positions. 04 Conclusion 4.1 Conclusion Applicability: Short-process casting technology is compared to the process route that requires hot rolling for billet opening. By tightly integrating melting and casting with subsequent rolling, it produces products close to the final products of aluminum processing plants, making it highly suitable for large-scale production of single products. Advantages: Low comprehensive energy consumption, small footprint, low unit cost, and minimal personnel occupancy. Disadvantages: Product performance still needs improvement, and product variety needs to be increased. Although the short-process technology cannot completely replace hot rolling, its advantages in producing certain large-scale single products are still significant. Therefore, vigorously developing short-process technology is imperative! 4.2 Conclusion Click to view the special report on AICE 2025 SMM (20th) Aluminum Industry Conference and Aluminum Industry Expo

The magnitude of surface wetting tension is commonly referred to as the "dyne value," with its accurate term being the "surface tension coefficient." Ultra-thin aluminum foil is more prone to defects such as surface cross-grain and scratches during the rolling process, and it tends to have more surface oil than conventional products, leading to situations where the dyne value does not meet standards. Factors influencing defects include the strength of the rolling oil film, roll crown, roll roughness, and pass reduction rate. 5. Pinholes (numerous pinholes, prone to breakage) As the thickness of battery aluminum foil decreases from the commonly used 12μm-15μm to 9μm-10μm, the adverse effects of pinholes gradually become apparent. They may cause breakage during foil rolling production and during the rolling process of pole pieces, especially in the blank areas of the pole pieces. However, battery manufacturers not only do not lower their requirements for the number and diameter of pinholes due to the thinning of aluminum foil but instead demand higher standards. Theoretically, the fewer the pinholes and the smaller their diameter, the better. Pinholes (numerous pinholes, exceeding standards) Excessive localized dense pinholes can prevent normal slitting, affecting the yield of aluminum foil. Reducing pinhole defects (1) Quality control of raw materials: ① Strictly control the purity of aluminum ingots to reduce impurity content; ② Ensure the uniformity of batch alloy composition to avoid pinholes caused by composition segregation, phase aggregation, or local microstructure abnormalities; ③ Use effective refining and degassing processes during melting; ④ Employ superior filtration and purification devices to remove inclusions and oxide scales from the aluminum melt. The production of ultra-thin aluminum foil requires even stricter standards. (2) Stable rolling process: ① Reasonably control rolling speed to avoid surface cracks and pinholes caused by excessive speed; ② Optimize reduction to prevent uneven internal microstructure deformation and stress concentration, which can lead to pinholes; ③ Ensure roll quality and regular maintenance, selecting rolls with good surface quality and high precision to maintain surface smoothness and uniformity, reducing pinholes caused by roll defects. (3) Strengthen clean production: Implement reasonable clean production processes in casting (hot rolling), cold rolling, and foil rolling to ensure good mill and production environments. (4) Install online pinhole detection equipment to monitor pinholes on the aluminum foil surface in real-time, promptly identify and handle products with pinhole defects, and adjust production process parameters based on detection results. 6. Edge quality Ultra-thin aluminum foil is more prone to defects such as edge burrs, edge waves, edge scratches, and end-face aluminum powder during the slitting process. Factors influencing defects: equipment precision, slitting tool quality/lubrication/angle, aluminum foil flatness, and operator skill. Performance challenges of ultra-thin battery aluminum foil In terms of performance, mechanical property requirements are increasingly stringent, with current and proposed performance indicators. As battery foil thickness decreases, strength and toughness tend to decline, making it more brittle and prone to breakage, posing significant challenges in processing and usage. For example, during battery production processes such as coating and winding, ultra-thin battery foil must withstand certain tension and pressure. Insufficient performance can lead to issues like rupture and wrinkling. Poor mechanical properties can cause battery foil to easily break during use, affecting battery safety and stability. For instance, during battery charge and discharge cycles, the expansion and contraction of electrode materials may cause cracks in the battery foil, leading to internal short circuits and safety incidents. ► How to improve the performance indicators of ultra-thin aluminum foil? (1) Optimize the quality of raw and auxiliary materials: Select high-purity aluminum ingots and high-quality refining agents, additives, and intermediate alloys to avoid the impact of impurities on the performance of ultra-thin aluminum foil. (2) Optimize the ratio and content of alloy elements and add rare earth elements to improve the performance of ultra-thin aluminum foil. (3) Optimize heat treatment processes, precisely control annealing temperature, time, and cooling rate to achieve good comprehensive performance in aluminum foil. (4) Optimize rolling processes. Adopt multi-pass, small-reduction rolling methods to refine grains and improve the strength and toughness of aluminum foil. At the same time, control rolling speed and tension to avoid defects such as uneven thickness and surface scratches, enhancing surface quality and dimensional accuracy. Future predictions for ultra-thin battery aluminum foil The ultra-thin battery foil market is vast. In the future, the ultra-thin battery foil market will continue to grow. From a policy perspective, government support for the new energy industry continues to drive the development of new energy vehicles and energy storage, thereby boosting demand for ultra-thin battery foil. From a technological perspective, continuous innovation in battery technology, such as the development and commercialization of semi-solid, solid-state, and sodium-ion batteries, imposes higher performance requirements on ultra-thin battery foil and presents new market opportunities. From a market perspective, increasing performance demands in consumer electronics, industrial, and energy storage sectors will drive sustained growth in demand for ultra-thin battery foil. Additionally, in the aerospace sector, extremely high battery performance requirements, including high energy density, lightweight, and high reliability, make ultra-thin battery foil essential for enhancing battery performance in aerospace equipment under extreme conditions. To improve the energy density and performance of lithium batteries, the trend of thinning battery aluminum foil will continue, and the ultra-thin battery foil market is vast. Structural shortages are prominent. High-end ultra-thin aluminum foil (e.g., 8μm products) faces supply shortages due to high technical barriers and low yield rates. By 2025, the demand for ultra-thin aluminum foil is expected to increase, but capacity is concentrated in a few enterprises, exacerbating market differentiation. Cost and process bottlenecks Cost and price factors: Low yield rates result in high scrap costs, which significantly impact product prices. As technology advances and production scales up, costs are expected to gradually decrease, further driving market demand. Meanwhile, fluctuations in aluminum prices will also affect the price of battery aluminum foil, influencing the supply-demand relationship. The production of ultra-thin aluminum foil relies on high-purity aluminum ingots and precision rolling technology. Raw material fluctuations and process stability directly affect capacity release. Top-tier enterprises need to increase R&D investment to break through technical bottlenecks and produce ultra-thin lithium battery aluminum foil that is thinner, stronger, more conductive, and has better surface quality. Small enterprises face significant survival pressure due to limited technical capabilities and insufficient capacity, putting them at a disadvantage in competition with larger firms. Finally, it provides an introduction to the company and its product specifications. 》Click to view the AICE 2025 SMM (20th) Aluminum Industry Conference and Aluminum Industry Expo special report.
