Mono-crystalline Aluminum Oxide is also called Single Crystal Aluminum Oxide (SA). Its main material is bauxite, which is electrically fused under high temperature, being added with the right quantity of sulphide. It is blue and featured with high hardness and toughness, well-shaped grains and impact strength. The abrasive tools made of it are suitable for the grinding of stainless steel, high vanadium, high speed steel, especially for the easily-deformed, easily-burnt workpieces.
