Product Description
White corundum,is made from high quality alumina by being melted above 2000℃ 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.
