Chinalco Lightweight Research Alloy Ultra-Light and High-Strength Materials Helps the Successful Launch of "One Arrow and Five Stars"

Time：2021-12-09

At 12:12 Beijing time on December 7, 2021, the Ceres-1 (Yao-2) carrier rocket was successfully launched at the Jiuquan Satellite Launch Center, and launched Tianjin University-1, Lize-1, Baowen, The five small satellites of Jinzijing-5 and Jinzijing-1 03 were successfully put into the predetermined orbit, and the launch mission was a complete success.

The satellite launched this time uses a large number of ultra-light and high-strength magnesium alloy products independently developed by Zhengzhou Qingyan Alloy Technology Co., Ltd., and related components have achieved a weight reduction of 35-40%, which greatly improves the satellite's payload and specific impulse.

Zhengzhou Qingyan Alloy is a high-purity magnesium alloy product prepared by solvent-free vacuum melting technology, with a tensile strength of more than 300MPa and an elongation of 10%-20%. The high-performance magnesium alloy prepared by the company has the advantages of uniform composition, high specific strength, good corrosion resistance, easy cutting and good electromagnetic shielding performance, etc., and has been used in aerospace, transportation, electronic communication and other fields in batches. The successful entry of the satellite into orbit marks that the high-performance magnesium alloy products prepared by light research alloys have become another major contribution in the field of spacecraft applications after aluminum-lithium and magnesium-lithium alloys.

The company has built a full range of R&D and production bases for ultra-light and high-strength aluminum and magnesium alloys in response to the urgent need for weight reduction in aerospace, forming a domestic first-class laboratory research, small test, pilot test and mass production scale. With complete high-performance alloy casting - forging (rolling, extrusion) - precision machining - surface treatment - performance testing and other production lines, it can provide customers with full-process services from raw materials to finished parts.

In addition, the company creatively provides customers with five weight reduction solutions: ① Use stronger replacement of the original material, which can reduce the weight by about 5%; ② Use low-density aluminum-lithium alloy to replace the original material, which can reduce the weight 5-15%; ③ Use magnesium alloy to replace aluminum alloy, which can reduce weight by about 30%; ④ Use ultra-high-strength heat-resistant aluminum-copper alloy to replace titanium alloy to reduce weight by 50%; ⑤ Use castings to replace deformed aluminum alloys, which can make complex shapes The thin-walled parts can reduce the weight by 10%.

Zhengzhou Qingyan Alloy Technology Co., Ltd. always adheres to the business mission of "technology leads the future, develops lighter, stronger and more cost-effective high-performance non-ferrous alloys, and continuously creates value for customers". The development of new materials, new technologies, and new products required is our responsibility, and we focus on the research and development of high-performance magnesium alloys, magnesium-lithium alloys, magnesium rare-earth alloys, aluminum-lithium alloys and other high-light and super-strong materials to help the aerospace industry. Thrive!!
