White Fused Alumina

Category

Description

White fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency. White fused aluminum oxide becomes the first choice for the sandblasting technics, meanwhile, it is also the ideal material for abrasive and workpiece cleaning, and polishing. Comparing with brown fused alumina, white aluminum oxide is also characterized by its high purity, acid and alkali resistance, good thermal stability. It’s the high grade refractory materials.

Black fused alumina is an essential component used in production of bonded abrasives (grinding wheels) and coated abrasives (sandpaper), refractories, industrial floors. White fused alumina is reusable in compressed air blasting. It is a pure and very hard abrasive. Aluminium oxide is used to anchor pattern creation prior to coating or bonding, rust, scale removal, sweeping, matte surface finish of steel, stainless steel, aluminum, non-ferrous metals, glass, stone and other surfaces
