Product Description

          BROWN ALUMINUM OXIDE FOR ETCHING PROCESSING SANDBLAST 

Brown aluminum oxide also called Brown Fused Alumina, BFA is produced by a reduction fusion of high quality bauxites in more than 2200 ºC electric arc furnace.By type, there is section sand, F sand and P sand.Section sand 0-1mm, 1-3mm,3-5mm, 5-8mm is mainly for refractory.F sand F12#-F220# is applied for bonded abrasives grinding wheels, blasting media, and polishing.

P sand P12#-P220# is mainly for coated abrasives like sand paper.
