[0002] Magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: low density, high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load bearing capacity than aluminum alloy, and good resistance to organic and alkali corrosion. The main alloying elements are aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium. The most widely used is magnesium-aluminum alloy, followed by magnesium-manganese alloy and magnesium-zinc-zirconium alloy.
