Brown fused 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. Because Brown Fused Aluminum Oxide has a high bulk density and high hardness making it the perfect media for removing rust, mill scale, and surface contamination. The consistent particle size allows for a uniform surface finish and coverage. Additionally, BFA has a low friability which allows it to be recirculated on average, up to seven times. These characteristics reduce abrasive consumption, clean up, and disposal costs, increasing profitability.
