White fused alumina F280 D50:36.5±1.5um

WHITE FUSED ALUMINA F280 D50:36.5±1.5UM

White fused alumina is also called white fused aluminum oxide,white aluminum oxide,white corundum or white electrocorundum,and for short “WFA” or “WA”.

It is made from high purity of aluminum oxide by melting above 2000 in the electric arc furnace and cooling.
