Brown Fused Alumina (BFA), formed in electric arc furnaces, is the most common form of fused alumina and is one of the most widely used in abrasives for its hardness (Mohs hardness of 9) and toughness. It is used in a wide variety of applications – from grinding wheels and coated abrasives to media used in blasting and polishing.
