Product Details

White Fused Alumina is electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness

White Fused Alumina 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.
