Magnesium alloys have the highest relative strength (ratio of strength to mass). The specific stiffness (ratio of stiffness to mass) is close to aluminum alloy and steel, much higher than engineering plastics. In the elastic range, when the magnesium alloy is subjected to an impact load, the energy absorbed is half that of the aluminum alloy, so the magnesium alloy has good shock resistance and noise reduction performance.
The melting point of magnesium alloy is lower than that of aluminum alloy, and the die-casting performance is good. The tensile strength of magnesium alloy castings is equivalent to that of aluminum alloy castings, generally up to 250MPa, and the highest can reach more than 600Mpa. Yield strength, elongation and aluminum alloy are not much different.
Magnesium alloy also has good corrosion resistance, electromagnetic shielding performance, and radiation protection performance, and can be 100% recycled and reused.
