[SMM Aluminum Morning Meeting Summary: Destocking Provides Support for Aluminum Prices During Off-Season, Prices Expected to Fluctuate Considerably] On the macro side, the phone call between China and the US may lead to a de-escalation of the trade war, while the rebound in China's manufacturing PMI and improvement in export indicators in May provide demand support, indicating that the resilience of the domestic economy remains. Fundamentals side, the operating capacity of domestic electrolytic aluminum remains stable, and the reduction in casting ingot volume has temporarily maintained the destocking trend of domestic aluminum ingot inventory. Cost side, the impact of the Guinea mine incident on alumina prices has eased somewhat, and the real-time cost of electrolytic aluminum has declined slightly MoM. On the demand side, it faces dual pressures from domestic seasonal weakness and trade uncertainties. In the short term, the operating rate of domestic aluminum processing enterprises will be under pressure, and the off-season atmosphere will intensify. Overall, the current low inventory and the expectation of a higher proportion of liquid aluminum provide strong support for aluminum prices. However, the off-season pressure on the demand side limits the upside room. Spot aluminum ingot in major consumption areas may soon face a situation of weak supply and demand, and aluminum prices are expected to remain volatile and range-bound in the short term.

[SMM Aluminum Morning Meeting Summary: Signals of Easing Trade Frictions Transmitted, Aluminum Prices May Remain in the Doldrums in the Short Term] On the macro front, the phone call between Chinese and U.S. leaders conveyed positive signals of easing trade frictions. If this can prompt the U.S. to revoke unfavorable measures, it will further improve the external environment for the aluminum market. Coupled with the European Central Bank's interest rate cut, which provides a relatively direct and clear positive stimulus for aluminum prices and offers additional support. Fundamentals side, the operating capacity of domestic electrolytic aluminum remains stable, with a slight expected decrease in subsequent casting ingot volumes. Domestic aluminum ingot inventory temporarily maintains a destocking trend. Cost side, the impact of the Guinea mine incident on alumina prices has eased somewhat, and the real-time cost of electrolytic aluminum has declined slightly MoM. On the demand side, there is dual pressure from domestic seasonal weakness and trade uncertainties. In the short term, the operating rate of domestic aluminum processing enterprises will be under pressure, with the off-season atmosphere becoming more pronounced. New orders in sectors such as building materials, PV, and automobiles are all showing signs of weakness. Overall, the current low inventory and the expectation of a higher proportion of liquid aluminum provide strong support for aluminum prices. However, the overall bearish macro environment during the week has caused aluminum prices to face downward pressure at high levels, and the off-season pressure on the demand side limits upside room. Spot aluminum in major consumption areas may soon face a situation of weak supply and demand, with aluminum prices likely to remain in the doldrums and consolidate in the short term.

In 2024, China's industrial aluminum extrusion sector witnessed sustained growth in applications across NEVs (with projected sales exceeding 12 million units), aerospace, and low-altitude economy. However, the industry faced multiple challenges including persistently high and volatile raw material prices, technological bottlenecks, international trade frictions, and the cancellation of export tax rebates.

On April 16, at the AICE 2025 SMM (20th) Aluminum Industry Conference and Aluminum Industry Expo — Aluminum Die Casting Industry Development Forum, co-organized by SMM Information & Technology Co., Ltd., SMM Metal Trading Center, and Shandong Aisi Information Technology Co., Ltd., and co-sponsored by Zhongyifeng Jinyi (Suzhou) Technology Co., Ltd. and Lezhi County Qianrun Investment Service Co., Ltd., Wenping Zhu, Eaton (China) Investment Co., Ltd.'s global aluminum alloy casting expert, special expert/director, and senior die casting engineer qualification certification training lecturer, shared a comparison of low-pressure casting and high-pressure die casting processes, as well as their advantages and disadvantages. **Differences in Process Principles** **Low-Pressure Casting** Pressure range: 0.01-0.1 MPa (low pressure). Principle: Compressed air is used to slowly press molten metal from a sealed holding furnace into the mold through a riser tube. The metal fills the cavity from top to bottom under low pressure and solidifies under pressure. Characteristics: Smooth filling, good metal fluidity, fewer pores and inclusions. **High-Pressure Die Casting** Pressure range: 10-200 MPa (extremely high pressure). Principle: Molten metal is injected at high speed into a steel mold under high pressure (provided by the injection cylinder), rapidly filling the mold and solidifying under high pressure. Characteristics: Fast filling speed (millisecond level), suitable for complex thin-walled parts, but prone to gas entrapment. Low-pressure casting and high-pressure die casting are two common metal casting processes, mainly used for forming non-ferrous metals such as aluminum alloys and magnesium alloys. They have significant differences in principles, application scenarios, and product characteristics. **Comparison of Process Characteristics** **Low-Pressure Casting** Advantages: Good casting density, high mechanical properties, fewer pore defects, capable of producing larger parts. Disadvantages: Long cycle time, higher mold cost, not suitable for ultra-thin-walled parts. Higher production cost, wall thickness must be >3.5 mm, preferably over 4 mm. **High-Pressure Die Casting** Advantages: High production efficiency (multiple parts can be produced per minute), suitable for complex thin-walled parts, high surface precision. High dimensional accuracy, small machining allowance. Disadvantages: Internal pores are common in castings, usually not heat-treatable (pores may expand), extremely high mold cost. Wall thickness greater than 2 mm is sufficient. Low-pressure casting can design closed beams of any diameter, and its advantages in torsional stiffness of closed beams were introduced. High precision dimensions and ultra-thin wall thickness are significant advantages of die casting. Additionally, magnesium alloy high-pressure die castings were introduced. **Breakthroughs and Development Directions for Low-Pressure Casting** 1. Material Innovation: Breakthroughs in high-performance aluminum alloys • Development of high-strength and high-toughness alloys: To meet the needs of new energy vehicles and aerospace, develop new-type aluminum alloys (such as high-silicon aluminum, aluminum-lithium alloys) to improve the specific strength and high-temperature performance of castings. Tensile strength breakthrough of 380 MPa for A356. • Application of composite materials: Breakthroughs in casting technology for aluminum matrix composites (such as SiC particle-reinforced aluminum) to achieve higher stiffness and wear resistance, used for chassis and powertrain components. 2. Process Upgrade: Intelligence and efficiency improvement • Development of low-pressure casting methods with efficient cycles, • Riser tube casting technology, • Electromagnetic pump casting technology • AI algorithm optimization to improve yield and cycle time. • 3D printed sand molds/metal molds **Breakthroughs and Development Directions for High-Pressure Die Casting** Technological breakthroughs: Enhancing performance and process limits, mainly focusing on defect elimination • 1. Ultra-large integrated die casting Breakthroughs needed in mold material heat resistance, press tonnage (over 12,000 mt), and vacuum technology. • 2. Popularization of vacuum high-pressure die casting (VHPDC) Reducing pores through vacuum (porosity 150℃). 3. Efficient application of secondary aluminum Trend: Improving the purity of secondary aluminum through refining technology (Fe content <0.15%), reducing costs and carbon emissions. • The application scenarios and development of magnesium alloy high-pressure die casting and semi-solid die casting, as well as the development and research of magnesium alloy raw materials suitable for die casting, were also elaborated. **Breakthroughs and Development Directions for Both Casting Processes** • Green Manufacturing: Low-carbon and circular economy 1. Energy-saving equipment upgrade: Servo motor-driven die casting machines (energy consumption reduced by 40%), waste heat recovery systems. 2. Environmental protection release agents and coatings: Trend of replacing oil-based agents with water-based release agents, chromium-free passivation treatment. 3.

Currently, the aluminum industry is at a critical juncture of profound transformation and rapid development. From an industrial dynamics perspective, the global aluminum industry is actively responding to the call for green development, accelerating the transition to cleaner production. From an industrial status perspective, China holds a dominant position in the global aluminum supply chain. However, China's dependence on bauxite imports remains high. Against this backdrop, US tariff policies have had a significant impact on the global aluminum industry. Facing the challenges posed by US tariffs, Chinese aluminum companies are actively seeking countermeasures. On one hand, they are accelerating their layout in the high-end aluminum sector, increasing R&D investment, and driving product transformation towards higher value-added products, such as aviation plates and power battery foils, whose exports are gradually increasing. On the other hand, they are vigorously developing the secondary aluminum industry, as the energy consumption of secondary aluminum is only 5% of that of primary aluminum, aligning with green development needs. Some companies are using transshipment trade through third countries like Malaysia and Thailand to reduce tariff costs. Others are actively applying for green certifications, reducing export costs through digital carbon management systems, and establishing hydropower aluminum bases in the southwest to increase the proportion of green electricity usage, thereby meeting international market demand for green aluminum products.
