White Fused Aluminium oxide (white corundum)

Usage : Grinding, Polishing, bonded abrasive, Coated abrasive, Sand blasting, Foundry, Refractory, Anti-skidding material, Brake material, Ceramic filter, sand blasting, dental mold polishing

WHITE  FUSED  ALUMINIUM OXIDE
Code: RWWA
Its main material is alpha alumina,, which is electrically fused in high temperature 2000℃. It is pure white and high hardness, 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 , sand blasting. dental mold polishing and so on.
