Black fused alumina is fused from high quality bayer aluminum in high temperature. Its hardness is higher but toughness lower compared with Brown Aluminum Oxide. It is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat. It can withstand acid and alkali erosion, with high temperature resistance and good thermo stability. | |
Application of black fused alumina 1.White Fused Alumina For Free grinding, such as glass industry. 2.White Fused Alumina For Friction products and abrasion resistance ground 3.White Fused Alumina For Resin or ceramic bonded abrasive,such as grinding wheels,cutting off wheels. 4.White Fused Alumina For Refractory Raw material, Wear-resistant and fire-proof products. 5.White Fused Alumina For Grinding and polishing ,such as gringing stone, Grinding block, flap disc. 6.White Fused Alumina For Coated abrasives,such as abrasive paper,abrasive cloth,abrasive belt.
