Bond Abrasive White Aluminium Oxide Fused Alumina 99% WFA F24 F30 F36 Description: white fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency. White fused aluminum oxide becomes the first choice for the sandblasting technics, meanwhile, it is also the ideal material for sandblasting and workpiece cleaning, and polishing.
