brown alumina abrasive for Spain

Brown Fused Alumina for Abrasives

Brown fused alumina is based on high quality bauxite as raw material, mix with moderate anthracite and iron fillings, by melting at 2000℃ in electrical arc, then crushing, selecting and shaping to be various size. It has been the best aggregate and fillers of brown corundum refractory. Brown fused alumina. Brown fused Alumina is mainly used as a recyclable abrasive in blast cabinets and blast rooms. Because of its low iron content, alumina is often used in blasting operations where iron contamination on the non-ferrous metal substrate is not allowed. Aluminium oxide is a very hard and sharp abrasive that cleans rapidly. Brown Fused Alumina (BFA) is produced by a reduction fusion of high quality bauxites in electric arc furnaces. It is both a hard and tough material with high strength, making it an excellent abrasive grain for applications such as grinding wheels, sandpaper, blasting media, metal preparation, lapping, polishing, and grinding.


Brown Aluminum Oxide is designed for the pressure blasting of materials of almost every type, including: glass, granite, marble, and ceramic and it is also used for the preparation of surfaces prior to painting or bonding; as well as for light deburring, scale removal, and the generation of matte finishes.
