99.95% 99.9% Magnesium Engraving Plates AZ80 AZ91 With Certain Bearing Capacity
Magnesium alloys are alloys based on magnesium and added with other elements. Its characteristics are: low density (about 1.8g/cm3 magnesium alloy), high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloy, and good resistance to organics and alkali corrosion.
The main alloying elements are aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium. Currently the most widely used is magnesium aluminum alloy, followed by magnesium manganese alloy and magnesium zinc zirconium alloy.
Magnesium alloys are mainly used in aviation, aerospace, transportation, chemical industry, rockets and other industrial sectors. It is the lightest metal among practical metals. The specific gravity of magnesium is about 2/3 of that of aluminum and 1/4 of that of iron. It is the lightest metal among practical metals, with high strength and high rigidity.
