Description
White Fused Alumina / White Aluminum Oxide/White Fused Aluminum Oxide/Whit Corundum/WA /WFA
White Fused Alumina in arc furnace with high grade processed alumina as raw materials. It has higher hardness and slight lower toughness comparing with Brown Fused Alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives, polishing, precision casting and so on.
Usage:
1. For abrasive materials, sandblasting media.
2.For refractory raw materials, Precision casting.
