White corundum micro-powder is made from white corundum abrasive through chemical pickling, water overflow, drying, grinding, magnetic separation, screening and other processes. White corundum micro-powder has the characteristics of uniform particle size composition and high cleanliness.
High purity, strong self-sharpness, strong grinding force, good chemical stability, high temperature and corrosion resistance. The abrasive tool made of it has sharp grinding, low heating rate, high grinding efficiency, and less adhesion during use.
