It is often used as a reducing agent to replace titanium, zirconium, uranium, beryllium and other metals. It is mainly used for manufacturing light metal alloy, ductile iron, scientific instrument and Grignard reagent. It can also be used for making pyrotechnics, flash powder, magnesium salt, aspirator, lighting projectile, etc. Structural properties are similar to aluminum, and have various uses of light metals. They can be used as alloy materials for aircraft and missiles. But magnesium burns at the ignition point of gasoline, which limits its application.
