WA/WFA 99% Al2o3 for precision polishing of steel pipes
INTRODUCE
White fused alundum/fused al2o3 WFA for precision polishing of steel pipes belongs to electro-corundum. It is also be called white aluminum oxide, white corundum or white fused aluminum oxide. White fused alumina is obtained from the fusion of high purity calcined alumina in electric arc furnaces. Compared with brown fused alumina, white fused alumina is characterized with high alumina purity, high hardness, chemical stability, high melting point, and large crystal size. It is widely used in coated and bonded abrasives, polishing, precision casting, sandblasting and refractory raw materials.
