Brown fused alumina feature： Low Heat-treated:Low temperature treatment enhances the toughness of abrasive grain, also improves cleanliness and capillarity. Heat-treated abrasive materials can be used for the fabrication of grinding wheels, coated abrasives, and specialized industrial applications. High Heat-treated:High temperature treatment imparts a blue color to the abrasive grain, as well as enhances its toughness.

White fused alumina is made of high-quality aluminum oxide powder, and white corundum is obtained by fused extraction and crystallization. It has high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, and stable thermal properties. White corundum hardness slightly higher than brown corundum, slightly lower toughness, high purity, good self-sharpening, grinding ability,

Brown aluminum oxide for grinding cup wheels brown corundum Brown aluminum oxide is made of high-quality bauxite, anthracite and iron filings. It is cooled and smelted in a high temperature by more than 2000 degrees in an electric arc. It is crushed and shaped by a jaw crusher and a ball mill. After magnetic separation, the

Brown fused alumina is made from high quality bauxite by fusing in an electric arc furnace at high temperature. It has good toughness and high hardness. It is suitable for manufacturing of vitrified and resin bonded tools, and for lapping,polishin, and sand blasting and sand cleaning.It can be also used to make superior refractory products.
