High Quality White Fused Alumina Corundum Aluminium Oxide WA WFA for Sandblasting Refractory Materials Bonded/Coated Abrasives
 
White fused alumina is produced by bayer alumina in an electric arc furnace at high temperatures. The product shows higher hardness and lower toughness than that of brown aluminium oxide. The materials are used to grind high carbon steel, high speed steel and chilled steel. It can also be used as polishing materials and precision founding sand, spraying and coating materials, catalyst carrier, special ceramics and super refractory materials.
