1.white corundum 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 , polishing, precision casting and so on . 2.The main advantages of white corundum (1) does not affect the color of the workpiece;(2) can be used in the process of iron powder is strictly prohibited to blasting; (3) fine powder level is very suitable for wet sandblasting and polishing operations; (4) high processing speed and h igh quality; (5) the amount of iron oxide contained in the extremely low forbidden iron residue sandblasting operations; (6) After the pickling step to remove impurities, the alumina content is higher. 3.
