Product details


Brown Fused Alumina for Abrasive


Brown Fused Alumina also called Brown Fused Aluminum Oxide or BFA. This is a tough, long-lasting material. It is brown in color as it has a slightly higher level of impurities than white aluminum oxide. BFA has high bulk density and good hardness is ideal material for metal preparation, grinding, coasting, blasting, lapping, polishing, precision casting and etc.
