The conductivity of white corundum powder

The conductivity of white corundum powder depends on the manufacturing process. White fused alumina(White corundum) powder that has undergone chemical treatment and washing with pure water has high cleanliness and good flowability. The conductivity of high quality white corundum powder can reach below 200 μS/cm.

WFA powder with low electrical conductivity will not leave chloride residue on the workpiece during sandblasting and grinding. It is more beneficial for subsequent coating and improves the durability and corrosion resistance of the coating.
