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.
