BLACK FUSED ALUMINA MIXED WITH BROWN FUSED ALUMINA FOR COATED ABRASIVES

Black fused alumina is a dark gray crystal obtained from the fusion of high iron bauxite or high alumina bauxite in electric arc furnace. Its main components are α- Al2O3 and hercynite. It features with moderate hardness, strong tenacity,good self-sharpening, low grinding heat and less prone to surface burning, making it an excellent abrasion-proof material. Main Technical Data: AL2O3 62%MIN FE2O3 6-13% SIO2 25%MAX TIO2 2-4% Specification: Grit:F12-F400 Section Sand:3-5mm,1-3mm,0.4-1mm,0-1mm Applications: 1.Resin Cutting Disc; 2. Polishing stainless steel tableware; 3.Wear-resistant anti slippery surface such as anti skid road,bridge,parking floor,airport runway etc.; 4.Sandblasting; 5. Abrasive belt and flap wheel; 6. Fiber wheel; 7.Polishing wax. Advantages: 1.Little heat generated in surface,hardly to burn the work pieces , moderate hardness and high smoth finish is achieved with little surface discoloration. 2. better performance/price ratio
