WFA White fused alumina blasting aluminum castings

White fused alumina WFA is a high purity, synthetic mineral. It is manufactured by the fusion of controlled quality pure grade Bayer Alumina in an electric arc furnace at temperatures greater than 2000 ℃ followed by a slow solidification process. Strict control over the quality of raw materials and fusion parameters ensure products of high purity and high whiteness.
