It is understood that magnesium alloy is an important material required in the fields of aerospace, automobile manufacturing, and electronic communication. The use of magnesium alloy parts in automobiles can reduce their own weight and reduce fuel consumption. The use of magnesium alloys to make computer casings can enhance their seismic resistance and better protect internal parts. The high-strength heat-resistant magnesium alloy is a high-end new material in magnesium alloy. It is not only light in weight, high in strength, but also maintains its original performance in a high temperature environment without significant changes. At present, there are only two or three manufacturers who master this high-end magnesium alloy casting process in China.

In 2017, taking advantage of the demand for model products, Capital Aerospace Machinery Co., Ltd. began to explore the high-strength heat-resistant magnesium alloy casting process. This work is mainly undertaken by Tianjin Aerospace Long March Technology Equipment Co., Ltd. to which it belongs.

According to Gao Pengcheng, the deputy general manager of the company, for the alloy, whether it is the distribution ratio or the heat treatment process or the molding process, it will affect its final performance, and the magnesium is flammable. To avoid burning during the melting and molding process, it is necessary. A unique process. To this end, the project team members reviewed a large amount of information, analyzed the characteristics of high-end magnesium alloys, continuously improved, optimized, and tested, and finally developed a casting that meets the requirements.

Although Capital Aerospace Machinery Co., Ltd. entered the market late compared with other units that mastered the magnesium alloy casting process, it completely mastered the casting process in only 8 months and entered the high-end market in one fell swoop, fully demonstrating its strong technical strength.
