White Fused Aluminum Oxide Polishing Powder - China

price: contact company for price


White Aluminum Oxide is fused from high quality bayer

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.


The abrasive tools made of it are suitable for grinding high

carbon steel, high-speed steel and chilled steel. It can

also be used as lapping and polishing medium, precision

founding sand, coating materials, catalyst carrier, special

ceramics and super refractory materials.
