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.
