Product Description

High Bulk Density White Fused Alumina Corundum Aluminium Oxide WA WFA
 

White fused alumina 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.
