Bonded Abrasive white fused emery powder Bonded Abrasive white fused emery powder is produced by fusing calcined alumina in an electric arc furnace under carefully controlled conditions. It is white in color, a dense mineral and has predominantly large crystals of Alpha Alumina. Characteristics & Advantages of white aluminum powder: 1.high purity, 2.ability of self-sharpening, 3.better cutting, 4.less heat emit, 5.higher efficiency, 6.acid and alkali resistance, 7.good thermal stability Chemical Composition Chemical Composition Al2O3(%) Na2O(%) Grit range F4-F80 ≥99.50 ≤0.35 F90-F150 ≥99.50 ≤0.35 F180-F220 ≥99.30 ≤0.40 F230-F800 ≥99.10 ≤0.50 F1000-F1200 ≥99.10 ≤0.50 Application Packing & Delivery
