Brown fused alumina is widely used in bonded and coated abrasives for the grinding of metals. Produced by fusing calcined bauxite in a reducing atmosphere, this help in removing residual sulphur & carbon and improves toughness, thus an ideal material for vitrified abrasives usage. Our range is available in standard grit and powder sizes to meet varied needs of clients.
