White fused alumina powder /emery/corundum 1. Description: White Alumina powder is fused from high quality bayer aluminum in high temperature. Its hardness is higher but toughness lower compared with Brown Aluminum Oxide. It is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat. It can withstand acid and alkali erosion, with high temperature resistance and good thermo stability. 2. Applications: The abrasive tools made of it are suitable for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand, coating materials, catalyst carrier, special ceramics and super refractory materials. 3. Advantages: a. Use imported Bayer aluminum; assure the high quality of products. b. Equipped full line of test method. The laboratory is certified by government Inspection Bureau, that assures its quality stability. c. Products are classified chemical washed, non-washed, shaped, non-shaped, normal bulk density and high bulk density. All products will be supplied according to customers different requirements. 4.Size we manufacture: 8-5mm, 5-3mm, 3-1mm, 0-1mm 320mesh-0, 280mesh-0, 240mesh-0, 200mesh-0, 180mesh-0 F8, F10, F12, F14, F16, F20, F22, F24, F30, F36, F40, F46, F54,F60, F70, F80, F90, F100, F120, F150, F180, F220, F240, F280, F320F360, F400, F500, F600, F800, F1000, F1200 Chemical compositionsPhysical properties Al2O3 99.50min Color White SiO2 0.08max Bulk density 1.75-1.95g/cm3 Na2O 0.26max True density 3.95-3.97g/cm3 About us Zhengzhou Haixu Abrasives Co., Ltd, founded in 1999, is specialized in abrasive WFA white fused alumina oxide, Brown Fused Alumina, Mullite and other related products.
