White aluminmum oxide JIS#500 for metal polishing and grinding
White aluminum oxide JIS#500 for metal polishing and grinding is electrically fused in arc furnace with high-grade aluminum oxide powder as raw material. Compared with brown fused alumina, it is of higher hardness and slight lower toughness. It is also characterized by its high purity, ability of self-sharpening, high cutting rate, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. As abrasive material, it is widely used for bonded and coated abrasive, polishing, precision casting and so on.
white aluminum oxide used for abrasives,blasting,grinding,ceramic,rust removal,surface treatment,floor coating,abrasion resistant layer etc
