Brown Fused Alumina

1. Introduction: 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. 2. Deep Processed BFA Calcined BFA: Heating to 1050°C greatly improves the purity, toughness, strength, and wear-resistance of abrasives. Primary application: vitrified grinding wheels. Blue-Fired BFA: While turning grain-color dark blue, firing at 1350°C achieves far greater toughness and strength, much lower iron content, a very low coefficient of thermal expansion, and excellent hydrophilicity, all of which increase grinding performance and accuracy. Primary applications: coated abrasives (paper, cloth and belts) and heavy-duty grinding wheels. Ceramic-Coated BFA: Ceramic coating improves purity and hydrophilicity, reduces dust, and achieves grain surfaces that have greater toughness, strength, and roughness, and that are also more uniform in particle size. Primary applications: coated and bonded abrasives. Ceramic-Coated Blue-Fired BFA: These grains deliver all of the advantages of both Ceramic-Coated and Blue-Fired BFA. Primary application: coated and bonded abrasives, especially for use on hardened steel and other high-carbide materials. 3.
