Magnesium metal is a new type of lightweight and corrosion-resistant metal material developed in the 20th century. The application of magnesium is mainly concentrated in the four fields of magnesium alloy production, aluminum alloy production, steelmaking desulfurization and aviation military industry. It is widely used in automobile manufacturing and light industry. , metallurgical industry, chemical industry, electronics industry and instrument manufacturing.
It has superior properties such as low specific gravity, large unit weight strength and high chemical stability, which makes aluminum-magnesium alloy and its magnesium mold castings popular, and the metal magnesium industry has developed rapidly. The application of magnesium alloy in the automotive industry has the advantages of high strength, heat resistance, wear resistance and light weight, which makes it gradually replace the plastic products on the automobile and the steel parts with large specific gravity in the automobile industry, mainly replacing the original engine and steering wheel. , seat base and more. For example, the General Motors' Polaris V-8 engine has 15 pounds (6.8 kg) of magnesium molded parts and is assembled on a Cadillac. The company produced 25,000 in the mid-1990s. ~30000 such cars, this one needs magnesium, the United States General Motors
