Consumption structure and market analysis of magnesium and magnesium alloy materials

Magnesium alloy has excellent performance, so it is widely used in aviation, aerospace, transportation, 3C products, textile and printing industries. The motion inertia of magnesium alloy parts is low, and the effect is especially obvious when applied to high-speed moving parts. In addition, due to the low density of magnesium alloy, it is suitable for the parts which need to be moved and transported in the application. The wall thickness can be increased when preparing the same part at the same time, so as to meet the stiffness requirements of the parts and simplify the manufacturing process of the complex structure (such as bars and ribs) of the conventional parts to increase the stiffness. In addition, the medium temperature properties of magnesium alloys enable it to replace engineering plastics and resin matrix composites in aircraft and missiles; Its high damping performance has been applied to 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. 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. 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 flash and pyrotechnics. In recent years, faced with the exhaustion of resources 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. In Japan, magnesium as the magnesium alloy structure material is less than 10%, most of which is cast materials, a small amount of extrusion materials, forging materials.
