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

Characteristic High hardness, particle density, good circular single particles. The pure white color, without impurities, guarantee the wear-resisting layer or wear-resisting paper colour and lustre and transparency. The particle size distribution uniform concentration, single particle shape, with the least amount of biggest wear-resisting effect. It is selected commit suicide by hanging oneself more than two
