White fused alumina

RFQ Description

White fused alumina is electrically fused in arc furnace with high grade Bayer's process alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. Abrasives tools made of it are suitable for grinding high-speed, high carbon steel, etc. It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials, etc.Purpose Specification Chemical composition(%) Al203 Nao Cao F12-F80 99.0Min 0.5Max 0.4MaxFor abrasive F90-F150 98.5Min 0.6Max 0.4Max F180-F240 98.2Min 0.7Max 0.4MaxFor abrasive W1-W63 97.5Min 0.8Max 0.5 Max 0-1mm 99.0Min 0.5Max 0.4Max 1-3mm 99.0Min 0.5Max 0.4Max For Refractory 3-5mm 99.0Min 0.5Max 0.4Max 5-8mm 99.0Min 0.5Max 0.4Max 8-12mm 99.0Min 0.5Max 0.4MaxFor Refractory 0-180mesh 98.5Min 0.5Max 0.4Max 0-220mesh 98.5Min 0.5Max 0.4Max 0-320mesh 98.5Min 0.5Max 0.4Max abrasives, refractory, sandblasting
