1. White fused alumina description:
White fused alumina powder is made from high quality alumina by being melted above 2000 centigrade in the electric fixed furnace. It is characterized by high purity, great selfsharpening, 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 and painting material.
