Although the specific gravity of magnesium alloy is heavier than that of plastic, the strength and elastic modulus per unit weight are higher than that of plastic. Therefore, in the case of parts with the same strength, magnesium alloy parts can be made thinner and lighter than plastic parts. In addition, since the specific strength of magnesium alloy is also higher than that of aluminum alloy and iron, the weight of aluminum or iron parts can be reduced without reducing the strength of parts.
Magnesium alloys have the highest relative strength (ratio of strength to mass). The specific stiffness (ratio of stiffness to mass) is close to that of aluminum alloy and steel, and much higher than that of 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 250 MPa, and the highest can reach more than 600 MPa. Yield strength, elongation and aluminum alloy are not much different.
Scope of application: Magnesium alloys are widely used in portable equipment and the automotive industry to achieve the purpose of light weight.
