Product Description

 24# High Temperature White Aluminium Oxide for Grinding Wheel

White Fused Alumina (WA) is produced by bayer alumina in an electric arc furnace at high temperatures. The product shows higher hardness, higher bulk density and good cleanliness. The materials can be used to grind high carbon steel, high speed steel, chilled steel and so on. It can also be used as polishing materials and precision founding sand, spraying and coating materials, catalyst carrier, special ceramics and super refractory materials.

White Corundum/White Aluminum Oxide/White Fused Alumina are applied into many industrial fields due to its stable and great physical and chemical properties. It can be used for making bonded/coated abrasive tools, for grinding, polishing, lapping, blasting, precision casting, and refractory industry, aerospace industry, mobile phone and electronic industry, jewelry industry, hardware industry, ceramics, automobile parts, bearing, powder metallurgy and so on.

Why Choose Us?

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
