Advantages
1. Light weight. It is the lightest metal among all commodity metals at present, with a density of 1.736glcm3. It is similar to plastic, with good elasticity and rigidity, and is not easy to be deformed after long-term use.
2. Good castability, size stability, easy cutting, low scrap rate, can achieve high-volume, high-efficiency industrial production.
3. Magnesium and its alloy is a kind of environmental protection material, which has no pollution to the environment and high recovery rate of waste.
4. With good high temperature plasticity, various bar, pipe, plate and stamping parts can be obtained through pressure processing.
5. Good anti-electromagnetic interference and shielding performance, coupled with its excellent comprehensive mechanical properties, can be widely used in 3C products.
6. With good damping performance, it has a broad application prospect in the automobile industry.
Description
The melting point of magnesium alloy is lower than that of aluminum alloy. The tensile strength of magnesium alloy castings is similar to that of aluminum alloy castings, generally up to 250Mpa and up to 600mpa. The yield strength and elongation of aluminum alloys are similar.
The stability of magnesium alloy casting is higher than that of high pressure casting, so it is used in the shell and shielding material of mobile phone.

Using Area
Large aircraft, manned spaceflight, lunar exploration and other major national projects, military aircraft and key equipment in the military field put forward very strict requirements for lightweight and weight reduction.
Magnesium alloy material, which has the advantages of light weight, high specific strength, high specific stiffness, damping, electromagnetic shielding, excellent casting, machining performance and easy recovery, plays a critical role. It is an ideal material to realize light weight. It has been paid more and more attention and its application has gradually expanded.
With the development of high-strength magnesium alloy and the progress of its preparation and processing technology, magnesium alloy has been widely used in the field of aerospace to manufacture important components of aircraft, missiles, spacecraft and satellites, in order to reduce the mass of parts, improve the maneuverability of aircraft and reduce the launch cost of spacecraft.
