BROWN ALUMINUM OXIDE GRITS FOR BONDED ABRASIVES
Brown aluminum oxide is made by fusion in an electric arc furnace from a mixture of bauxite, anthracite and iron scraps at high temperature. It has brown color, high hardness and great toughness. No rusty spot, greatly improved grinding efficiency, applicable to make high quality vitrified and resin bonded abrasives.
The brown aluminum oxide grits for vitrified boned abrasives simply called “ABV”, and the grits for resin bonded abrasives called “ABR”
Our production standard can be GB/T, also can be FEPA, JIS, ISO, etc.. according to clients’ requirements.
Commodity: Brown Fused Alumina
Production Type: Tilting Furnace, Barmac Crushing, Air Blow Cleaning
