WHITE FUSED ALUMINA OXIDE – WFA

Its main material is alpha alumina,, which is electrically fused in high temperature 2000℃. It is white and its hardness is higher, but toughness lower than that of brown fused alumina. The abrasive tools made of it are suitable for the grinding of carbon steel, high speed steel and chilled steel. It can also be used as polishing materials and precision founding sand, spraying and coating materials, catalyst carrier, special ceramics and super refractory materials.
