White Fused Alumina
Its main material is bayer alumina, which is electrically fused in high temperature. 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 high 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.
