-
Category:Aluminum Oxide
SPEC:120#
Packaging:Bag Package/Small Bag Package
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.
