After high temperature and high heating, a layer of metal iridium composite material is plated on the surface of the material, and the special treated abrasive is made after calcination. After the fused alumina coated with iridium, the toughness is significantly improved, the surface is rougher, the hydrophilic ability is stronger, the self-sharpening property is increased, and the heat dissipation performance is improved. The abrasive products have the characteristics of high efficiency, long life, and not easy to burn the workpiece. As one of the professional white fused aluminium oxide suppliers in China, HAOYUN can provide you with quality white fused alumina powder wholesale. <br> <br>Description of Special Treated White Fused Alumina <br>Items Unit Index Typical <br>Chemical Composition Al2O3 % 99.00min 99.32 <br> SiO2 % 0.20max 0.09 <br> Fe2O3 % 0.10max 0.03 <br> Na2O % 0.40max 0.23 <br>Refractoriness ℃ 1850min <br>Bulk Density g/cm3 3.50min <br>Mohs Hardness --- 9.00min <br>Principal Crystalline Phase --- α-Al2O3 <br>Refractory Grade Grain mm 0-50, 0-1, 1-3, 3-5, 5-8 <br> Fines mesh -200, -325 <br>Grit (F Grade and P Grade) FEPA 8, 14, 16, 20, 22,24, 30, 36, 40, 46, 60, 70, 80, 90, 100, 120, 150, 180, 220, 240 <br> <br>Typical Physical Properties of Special Treated White Fused Alumina <br>01. <br>New Materials <br>Specail treated fused alumina abrasives are based on traditional abrasives, using new materials and technologies to improve the abrasive. <br>02. <br>Hydrophilicity <br>Compared with ordinary abrasives, the microhardness is increased by 10%, the toughness is increased by 10%, the hydrophilicity is increased by 35%, the grinding efficiency is increased by 30%, and the durability is increased by 30-50%, which is very helpful for the improvement of the quality of grinding wheel products. <br>03. <br>Raw Materials <br>Special treated fused alumina can also be used in precision casting molding sand, spraying materials, raw materials for special ceramic products, advanced refractory materials and other fields. <br> <br>As one of abrasive material suppliers, we can provide kinds of abrasive material for sale, if you have needs, please contact us.
