price: contact company for price

Product Introduction White corundum is made from high quality alumina by

being melted above 2000 Degrees Celsius 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.
