White fused alumina with high quality alumina oxide powder as raw materials, white fused alumina is produced by fusing and extracting from crystalliza

It is featured by high purity, self-sharpening, and acid-alkali and corrosion resistance, temperature tolerance. Compared with brown fused alumina, its thermal stability properties is slightly higher and toughness is slightly lower. The abrasive tools made by it are applicable for grinding high carbon copper and high-speed steel.

1.For Abrasive: This kind of 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, acid and alkali resistance, good thermal stability. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives.

3.for Sandblasting: White fused alumina for sandblasting abrasive is processed by high quality corundum from Rui Shi Abrasive Plant as raw material and utilized by unique advanced technology. It is characterized by short grinding time, high efficiency, good returns , low price and so on. In particular, its advantages such as high hardness, big specific gravity, good chemical stability and unique self-sharpening , it becomes the first choice for the sandblasting technics, meanwhile, it is also the ideal material for sandblasting and derusting, workpiece cleaning, and polishing.
