white aluminum oxide abrasive for polishing powder
White Aluminum Oxide is fused from high quality excellent aluminum in high temperature. Its hardness is higher but toughness lower compared with Brown Aluminum Oxide. It is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat. It can withstand acid and alkali erosion, with high temperature resistance and good thermo stability.
