BROWN ALUMINUM OXIDE FOR SANDBLAST MOLDS CLEAN
DESCRIPTION OF BROWN ALUMINIUM OXIDE
Brown Fused Alumina, also called Brown aluminum oxide, brown corundum, artificial corundum, BFA, etc, is produced by a reduction fusion of high quality bauxite in electric arc furnaces in more than 2200 ℃ electric arc furnace, and then crush to F 12#-220# grits by Barmac,
F sand F12#-F220# is applied for bonded abrasives grinding wheels, blasting media, and polishing.
