Brown aluminum oxide is obtained from fusion of high-quality bauxite. Main features are Good harness, high compression strength, good hydrophily and lower expansion coefficient.

There are F sand and P sand.

The F grits 12#-220# is widely used to produce Bonded abrasives grinding wheel, cutting discs, also for sandblasting.

P sand used to produce coating abrasives sand paper, sand belt, flap wheel, etc.

Commodity: Brown Fused Alumina
