The amount of magnesium in modern industry has increased for its light weight, strong toughness, good ductility and other characteristics. Magnesium mainly uses in production of magnesium alloy and aluminum alloy ingot of high purity; iron and steel smelting of desulfurization agent; titanium, zirconium, hafnium, uranium, beryllium and other metal smelting reducing agent; cathodic protection of chemical tanks and underground pipelines. In practical applications, the primary use of magnesium is to produce aluminum alloy. Magnesium is an important component point of aluminum alloy; it can enhance the alloy's mechanical strength, improve mechanical processing performance. As the alloy of magnesium and other metals (aluminum, zinc, manganese, etc. ) have strong unit weight of strength and high chemical stability, magnesium has been widely used in the cause of automobile and aviation.
