Characteristics of magnesium alloy

The specific gravity of magnesium alloy is 2/3 that of aluminum and 2/9 that of iron, so it is very light.
The melting point of magnesium alloy is almost the same as that of aluminum, and the boiling point is relatively low at 420 °C.
A large amount of magnesium powder reacting violently with water will result in ignition, and the high temperature magnesium will react with the oxygen in the air to cause combustion.
