White corundum(WA) is manufactured from Aluminia powder by crystal electro-fusion process at high termperature of over 2000C.Its hardness is a little higher and toughness is a little lower than brown corundum.It has the advantages of high purity, good sharpness, strong grinding force, less calorific value, high efficiency, good acid/alkaline corrosion resistance,high temperature resistance, good thermal stability, etc.
