• 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.
