So commonly used reducing agent, to replacement of titanium, zirconium, uranium, beryllium and other metal. Mainly used in the manufacture of light metal alloys, ductile iron, scientific instruments and dehydrogenation desulfurizer Grignard reagent, but also can be used for system fireworks, flash powder, magnesium salt and so on. Magnesium is an important material for the aviation industry, magnesium alloy and the sum used in the manufacture of aircraft engine parts; Magnesium is also used in the production of photographic and optical equipment, etc.; magnesium and its alloys of non-structural applications is broad; magnesium as a strong reduction agent, but also for titanium, zirconium, beryllium, uranium and the production of hafnium.
