White Fused Alumina/White Corundum

White fused alumina/White aluminium oxide (WA)is electrically fused in the furnace with high grade bayer processed alumina as raw material..It has high purity,ability of self-sharpening,better cutting,less heat emit,higher efficiency,acid and alkali resistance,good thermal stability.Abrasives tools made of it are suitable for grinding high-speed,high carbon steel ,etc.It also can be used as materialsfor grinding and polishing,precision casting,spaying and coating, medium body for chemical industry,special ceramics and high-grade refractory materials,etc.
