As a key material in fields such as aerospace, integrated circuits, and high-speed rail transportation, high-end copper alloys are increasingly gaining strategic importance. Despite China's copper semis production and consumption ranking first globally for consecutive years, with a self-sufficiency rate of 96% for general copper semis, high-end copper alloy products still heavily rely on imports. To address this "chokehold" challenge, SMM recently initiated an industry resource integration proposal, 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 a "major material producer" to a "powerful material producer". Ningbo Ouke Metal Materials Co., Ltd., as a partner, actively participated in the joint production of the sourcing guide, jointly promoting the healthy and rapid upgrading of China's copper alloy materials industry chain. Ningbo Ouke Metal Materials Co., Ltd. , established in 2018, spans 30 mu with a construction area of 12,000 square meters and an annual production capacity of 8,000 mt of copper alloy rods and wires. It is a producer specializing in the R&D and production of high-precision copper alloy materials. The company mainly engages in the production and processing of wire and rod materials for alloys such as tin bronze, red copper, tellurium copper, and brass, offering a comprehensive range of copper alloy series grades, advanced production and inspection equipment, and forming advantageous industrial layouts in multiple sectors. The straightness and tolerance of the company's products can meet the processing requirements of various types of automatic lathes and CNC turning machines, with straight bars available in specifications ranging from φ0.8 to φ100mm in diameter. The grades involved include: 1. Tellurium copper C14500, oxygen-free tellurium copper (new energy high-voltage fast charging series), red copper T2, oxygen-free copper TU1, TU2, etc., with coil stock used for cold heading terminal series (500 kg per single coil) 2. Lead-free copper HBi59-1.5 (conventional C6801), HBi59-2 (applied in easy-to-machine e-cigarette through-hole parts, spring pins, etc.) 3. Tin bronze QSn4-3 (military 1.2, 1.3, 1.5, 2.0, etc., diameter stockpiling), C54400, QSn6.5-0.1, C5191, C51000, QSn10-1, C93200 4. Aluminum bronze QAl9-4, QAl10-4-4, C63000, C63200 5. Conventional brass and environmentally friendly national standard copper: 62, H65, H70 copper, HPb59-1, C3604, etc. 6. New-type elastic easy-to-machine materials: C19160, C31400, C18700, C14415, applied in NEV, military, and aerospace fields 7. Agency sales and polishing, beryllium copper C17300, C17200, QBe2, C17510, etc., can provide high-precision ground bars with a tolerance control of 0.005mm Contact Information Wu Yonglin, Deputy General Manager, 13685735155 (same as WeChat) Click here to receive the "2026 China Copper Alloy Materials Sourcing Guide" for free SMM Contact Person Lin Junfeng 183 2622 3112 linjunfeng@smm.cn

On April 22, at the CCIE 2025 SMM (20th) Copper Industry Conference & Copper Industry Expo – Copper Pipe and Billet Processing Industry Development Forum, Lao Xicai, General Manager of Guangdong Weiqiang Copper Technology Co., Ltd., shared insights on the impact of the metallurgical quality of brass ingots and brass bars on the microstructure and properties of sanitary ware products.

With the rapid advancement of technology, tin solder, as an indispensable basic material in the field of electronic manufacturing, has become increasingly important. From precision PCB circuit boards to dazzling LED lighting, from cutting-edge semiconductor packaging to the booming PV industry, the application of tin solder is ubiquitous, playing a crucial role in the stability and enhancement of product quality. At the same time, we should also recognize that the rise of the manufacturing industry in Southeast Asia has brought new growth points to the tin solder market. This region is rich in labor resources, has relatively low costs, and enjoys strong government policy support, attracting numerous international electronics companies to establish operations. As these companies continue to grow and expand, the demand for tin solder will also continue to increase. To provide a more comprehensive display of the distribution pattern of tin solder enterprises in China and Southeast Asia, and to more accurately meet market demands, Haoyu Electronic Materials Co., Ltd. has partnered with SMM to initiate the creation of "2025 China and Southeast Asia Tin Solder Procurement Guide (Bilingual Edition)" . Through this map, the industry can gain a more comprehensive understanding of the current application status of tin solder in China and Southeast Asia, empowering enterprises in their layout and industrial development. Haoyu Electronic Materials Co., Ltd. was established in 2019 and is a high-tech manufacturing enterprise integrating production, sales, and service. The company is located in the manufacturing hub of Ho Chi Minh City, near the Ho Chi Minh City High-Tech Park, with convenient transportation. To better serve customers, the company opened a new factory in Long An Province in 2021. Over the past few years, we have understood that technical requirements, product quality, and service capabilities are the keys to building strong trust with our customers. For many years, we have been committed to the research and development of lead-free solder materials, with solder wire, solder paste, and solder bars as our main products. Our years of product research and development have increased our market share by five times. Among them, the Sn-Cu-Ag series solder bars have received widespread recognition from customers.
