White fused aluminum oxide powder is an excellent polishing powder for stainless steel, aluminum alloy, copper, glass, and other materials. White fused aluminum oxide powder from us is an electrofused aluminum oxide powder. It is an aggressive grinding powder with high hardness, good toughness. White aluminum oxide is suitable not only for direct polishing with a micro polishing machine, but also suitable for making lapping products such as polishing wax, polishing stone, polishing liquid, etc. In the meanwhile, white aluminum oxide is an ideal additive for wear-resistance coating and ceramics.
