White fused alumina JIS#400 for metal polishing and grinding

Product Description

White aluminum oxide  is electrically fused in arc furnace with high-grade aluminum oxide powder as raw material. Compared with brown fused alumina, it is of higher hardness and slight lower toughness. It is also characterized by its high purity, ability of self-sharpening, high cutting rate, less heat emit, higher efficiency, acid and alkali resistance, good thermal stability. As abrasive material, it is widely used for bonded and coated abrasive, polishing, precision casting and so on.

Technology

white aluminum oxide
This kind of white aluminum oxide size 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.
