White Fused Alumina 30mesh grit for Sandblasting
White Fused Aluminais made of high quality aluminum oxide powder as raw material, refined and crystallized by electric melting. It has high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance and stable thermal performance. Its hardness is slightly higher than that of brown corundum.It is suitable for grinding fine grain abrasive such as high carbon steel, high speed steel and stainless steel.
