Specification :

White fused alumina / White Aluminum Oxide / WFA / WA
WA / white fused alumina: white fused alumina is electrically fused in arc furnace with high grade Bayer's process 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, acid and alkali resistance, good thermal stability. Abrasives tools made of it are suitable for grinding high-speed, high carbon steel, etc. It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials, etc.
White fused alumina also can be called as White Aluminum Oxide, WFA or WA
Use of Whit fused alumina: first as the abrasive materials, second as the refractory materials, third as the sandblasting abrasive materials
Chemical composition (%) of white fused alumina:
Al2O3 Na2O
99.00%Min 0.5%Max
Size of white fused alumina:
For abrasive materials: F12#--F80#, F90#--F150#, F180#--F240#; W1#--63#
For refractory materials: P(0-1mm, 1-3mm, 3-5mm, 5-8mm, 8-12mm.), fine powder: 0-180#, 0-240#, 0-320#
(Attention: F means the specification for bonded abrasives and sandblasting; W means micro powder)
