It has white color, high hardness (Mohs hardness: 9.0), high melting point(2200 degree centigrade), high purity (AL2O3:99.5%Min), high temperature resistance characteristic, very stable chemical characteristic.The powder and grit are widely used for abrasive media, sandblasting, polishing and grinding on metals surface treatment, such as steel, stainless steel, high carbon steel, high speed steel. It is also used for refractory materials, abrasion resistance additive, hardware decoration. And it is commonly used for making ceramics at industrial grade, food grade, for electronics. For beauty additive, it is also commonly in recent years.
It has higher hardness and toughness, white color and very nice appearance with high purity of Al2O3 99%min.The abrasive tools made of it are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel. The powder of finer grit size, can also be used for abrasive making, precision casting and high-grade refractory, for sandblasting etc.

Now ,the raw material industry has come out vicious competition with price war in China . In order to get more profit , some suppliers think out many strange methods under upon Low price. For example, they add something which very cheap but the appearance is very similar with the goods. No one can find any difference via appearance. The consequence is that clients diffcult to get goods which have surprisingly good effect.I hope that more customers can avoid this kind of loss through my own efforts. Jointly create a good market order
