Because magnesium alloy is very light, it is mostly used in industrial sectors such as aviation, aerospace, transportation, chemical industry, and rockets. Its density is 1/4 of that of iron, its specific gravity is about 2/3 of that of aluminum, and it is the lightest of practical metals.
Magnesium alloy is often used as the skeleton of SLR cameras because of its low density, high strength, and certain anti-corrosion properties. In general, high-end and professional digital SLR cameras will use magnesium alloy as the frame, which is strong and durable, and feels very good.
Magnesium alloys play an indispensable role in aerospace and are widely used. Magnesium alloys are used in aerospace because of their high density, light weight, and easy stretching characteristics, which can reduce the load on various aerospace vehicles, further reduce the fuel load of the aircraft, and reduce the weight of the overall aircraft. Reducing more makes the aircraft fly farther.
Magnesium shavings are lively and flammable at high temperature. During the cutting of magnesium alloys, most of the incisions of magnesium chips are unoxidized magnesium and magnesium alloys. Because metal magnesium has a low ignition point and minimum ignition energy, and the chip is thin and small, and has a large specific surface area, it is easy to burn in the air under high temperature environment.
