Pink fused aluminium oxide Pink fused alumina, also called pink fused aluminium oxide, chromium aluminum oxide, abbreviated as "pa", belongs to the group of artificial corundum. It's made from fusion of high purity alumina powder and chromium oxide in electric arc furnace. Because of its chrome content, it's a pink color material. Its main content is aluminium oxide(al2o3), with little content(about 0.7% chromium oxide and about 0.3% sodium oxide(na2o). Pink fused aluminium oxide is a hard, tough, self-sharpening, low magnetic, coarse grits, pure and clean abrasive material. Compared to white fused aluminium oxide, it has similar hardness, while better strength and cutting side. It's widely used in production of vitrified grinding wheel, resinoid grinding wheel, cutting discs, grinding head and other abrasive tools, also for sandblasting abrasvies, polishing, free grinding, cutting etc. Physical and chemical properties True gravity: ?3.9 g /cm3 Bulk density: 1.40-1.91 kg / m3 Mosh hardness: 9 Color: pink, light purple Melting point: 2200 celcius degree Sizes: f8-f220 Applications of pink fused aluminium oxide Production of ceramic and vitrified grinding wheel Grinding head and other bonded abrasives and coated abrasive tools Refractory bricks, glass oven and other refractory materials Free grinding and polishing on precision devices, mahinery parts, ceramics, precision casting etc. Clean, sand blast, polish, rust remove metal and non-metal parts
