What are the main raw materials of magnesia chrome bricks?
Magnesium alloys are alloys based on magnesium and other elements. Its characteristics are: small density (1.8g/cm3 magnesium alloy or so), high specific strength, high modulus of elasticity, good heat dissipation, good shock resistance, greater impact load capacity than aluminum alloy, good resistance to organic and alkaline corrosion. The main alloying elements are aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium.
At present the most widely used are magnesium aluminum alloy, followed by magnesium manganese alloy and magnesium zinc zirconium alloy. Mainly used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors. In practical metals, it is the lightest metal, and the specific gravity of magnesium is about 2/3 of aluminum and 1/4 of iron. It is the lightest metal in practical metals, high strength and high rigidity.
