Mg99.95 high purity magnesium ingot with low specific gravity, high chemical stability, high strength per unit weight and other superior properties, making aluminum Mg99.95 high purity magnesium ingot and its magnesium mold castings are popular, but also make the rapid development of magnesium metal industry. Automotive industry application Mg99.95 high purity magnesium ingot has the advantages of high strength, heat resistance, wear resistance and light weight, gradually replaced the automotive industry in the plastic products and specific gravity of steel parts, mainly engines, seat bases, steering wheels and so on. Because magnesium combustion is mainly violent reaction with oxygen, fire extinguishing to isolate the air as the main principle of fire extinguishing.
Magnesium is a more important non-ferrous metal, it is lighter than aluminum, can be well with other metals constitute a high strength alloy, magnesium alloy has a lighter specific gravity, higher than the strength and stiffness, good thermal and electrical conductivity, corrosion resistance and good damping damping and electromagnetic shielding properties, easy to process molding, easy to recycle and other advantages.
