Single crystal fused alumina (also known as 32A) abrasive: the use of special production process, the natural crystalline grain size produced goods, rather than mechanical crushing results. Heat is a very good toughness, high abrasive material for the production of advanced cutting and grinding tools for high-vanadium high speed steel, stainless steel, titanium high hardness, high toughness materials, grinding, especially the use of easy to wear and easy deformation of dry grinding of the workpiece burn
