Discription:

White Fused Alumina(WA),also called White  Aluminium Oxide, white corundum ,belongs to the electro fused artificial corundum group It's obtained from reduced fusion of high purity calcined alumina in electric arc furnaces. when cooled down and crushed into different sizes for different applications.  It is characterized by high purity (Al2O3 content≥99%), great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance, which make it to be prefect raw material for all kinds of abrasive tools, including grinding grinding high carbon steel, high speed steel, stainless steel and and other fine-grained abrasives, it also can be used for precision casting and Advanced refractory materials Does not affect the color of the machined part;Low iron oxide residue , suitable for the work of forbidden iron residue
