The development history of magnesium material application

Due to its light specific gravity, high specific strength and stiffness, good thermal conductivity and electrical conductivity, good damping and electromagnetic shielding properties; At the same time, it is easy to process and form, and waste is easy to recycle. As the shell structure of electronic device, such as mobile communication laptop, it can replace plastic to meet the requirements of light, thin, miniaturization and high integration of products. Therefore, magnesium and magnesium alloys have become the preferred materials for modern automobile, electronics, communication and other industries. They are known as the "green engineering materials of the 21st century" and have broad commercial application prospects.

With the maturity of smelting technology, the production cost of raw magnesium has decreased greatly. The smelting and recovery energy consumption of magnesium alloy is lower than that of aluminum alloy. In addition, magnesium is easy to process and saves mould and tool, so the price of magnesium alloy per unit volume is lower than that of aluminum alloy. The price and technology bottlenecks that hinder the mass application of magnesium alloys have begun to be broken through.

Because of the optimistic about the existing and potential market of magnesium alloy, some large foreign enterprises and consortiums have also invested huge capital in the development and research, in order to constantly develop new magnesium alloy die casting technology and products, to seize the market. Therefore, since the 1990s, magnesium, as a rapidly rising engineering metal material worldwide, has maintained a rapid growth rate of more than 20% per year, which is unprecedented among modern engineering metal materials.
