high purity WFA / WA 1.experienced factory 2.ISO9001,2000 3.high purity Al2O3,more than 99.5%

high purity WFA / WA

is made from high quality alumina by melting above 2000°C in the electric arc furnace and then cooling. It is with high purity, great self-sharpening, acid and alkali resistance, high temperature 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.

Applications:

It can be made to the abrasives, suitable for sandblasting and grinding high carbon steel and staining steel and other fine-grained abrasive; also be used for precision casting and high-refractory materials.
