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 ℃ 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.
Commodity: Brown Fused Alumina
Production Type: Tilting Furnace, Barmac Crushing, Air Blow Cleaning
