Magnesium alloys have also long been used in the manufacture of a variety of military equipment, such as tent skeletons, mortar mounts and missile casings. In addition, the moderate temperature of magnesium alloys makes it possible to replace engineering plastics and resin matrix composites in aircraft and missiles; Its high shock absorption function is applied in the electronic compartment structure of aircraft and missile. Its low transmission resistance to X rays and thermal neutrons makes the magnesium alloy especially suitable for X ray frame and nuclear combustion feed box.

In addition, because of the low density of magnesium alloy, it is suitable for the parts which need to be moved and transported in the application. At the same time, the wall thickness can be increased when preparing unified parts, so as to satisfy the stiffness requirements of parts and simplify the manufacturing process of complex structures (such as bars and ribs) that increase the stiffness of conventional parts. Magnesium alloy parts have low motion inertia, and the effect is especially significant when applied to high-speed moving parts.

Magnesium alloy has excellent function, so it is widely used in aviation, aerospace, transportation, 3C products, textile and printing and other industries. In recent years, in the face of resource exhaustion and the need of environmental protection and safety, the development and application of magnesium alloy in automobiles, motorcycles, electronic products and other aspects has attracted great attention all over the world.

In the United States, magnesium is used as a structural material for magnesium alloys, accounting for about 30% of the total magnesium requirements, and the remaining 70% is used as non-structural materials, such as additives for aluminum alloys, spheroidizing agent for ductile iron, etc. Tiny magnesium alloy particles containing less than 30 percent aluminum produce dazzling white light when burning. This white light is better than natural light for photography, so it is widely used in photographic flashbulbs and fireworks. In Japan, magnesium as the magnesium alloy structure material is less than 10%, of which a large sector is forging materials, a small amount of extrusion materials, casting materials.
