Introduction
Brown aluminum oxide, otherwise known as Brown Fused Alumina or BFA, is produced through an electric arc furnace process. Brown fused aluminum oxide is both a hard (Mohs hardness 9) and tough material with high strength, making it an excellent abrasive grain raw material for applications such as blast media, sandpaper, grinding wheels and abrasive discs, rolls, belts and pads. Its thermal properties make it an excellent raw material for refractory applications, as well.
