Product Details

Al2O3 99% white fused alumina/corundum powder for plasma spraying

White fused alumina/ White Aluminium Oxide is fused from high quality excellent aluminum in high temperature. Its hardness is higher . It is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat. It can withstand acid and alkali erosion, with high temperature resistance and good thermo stability.

White Fused Alumina belongs to the group of electro-corundum. It is produced by controlled melting of alumina in an electric arc furnace. White fused alumina is iron-free, ultra pure and extremely hard. And it can be applied to so many fields as following
