BLACK ALUMINIUM OXIDE / EMERY FOR SANDPAPER,FIBER WHEEL,POLISHING WAX

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 alternative abrasion-proof material. Specifications: Grit: F12-F400 Section Sand：3-5mm,1-3mm,0.4-1mm,0-1mm etc. Black Fused Alumina Applications: 1.Resin Cutting Disc; 2. Polishing stainless steel tableware; 3.Wear-resistant anti slippery surface; 4.Sandblasting; 5. Abrasive belt and flap wheel; 6. Fiber wheel; 7.Polishing wax. Advantages: 1.Strong cutting force and good self-sharpening to improve the efficiency; 2.Little heat generated in the surface,hardly to burn the workpiece,moderate hardness and high smoth finish is achieved and little color discoloration; 3. high price/performance ratio
