White Aluminum Oxide Polishing Media Grit


Product Information

White fused aluminum oxide is a very high purity oxide, and thus recommended when contamination is an issue to be considered.  It is obtained from the fusion of high purity calcined alumina in electric arc furnaces.  The result is a product with high hardness, high friability, high purity, high melting point, and large crystal size.  The main difference between white and brown fused aluminum oxides is purity and friability.  White is highly pure and highly friable, breaking down quickly.  Brown fused is less pure and has a low friability rating, thus it will not break down nearly as quickly.  However, the hardness rating of the two is about the same.  Friability is not the same as hardness.
