Home - Product - Bonded Abrasive - White Fused Aluminium Oxide

WAE-17

It is a 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 an abrasive, it is suitable ofr grinding high-speed, high carbon steel, as loose grains, it widely used for polishing, precision casting, spring and coating.
