White fused aluminum oxide

White fused aluminum oxide, is made from high quality alumina by being melted above 2000°C in the electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency. White fused alumina can be made into all kinds of abrasives, suitable for grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives; it can be also used for precision casting and high-refractory materials. 

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.

Performance and advantages 

Pure, clear, white aluminum oxides.The most friable aluminum oxide and due to its high purity and largecrystal size, the crystals fracture comparatively swiftly, constantly exposing fresh cutting crystals to the workpiece.These materials are widely used in precision finishing of wood, leather, rubber, glass, etc. and in the grinding of heat sensitive alloys, taking advantage of its friability and cool cutting ability.
