It is characterized by its high hardness, good toughness and sharp shape in size. It is suitable for make grinding wheels, cutting wheels, mounted wheels, sharpening stone, abrasive media, and also suitable for blasting material of cleaning machine, surface gringing, lapping or polishing. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: Carbon Steel, General-purpose Alloy Steel, Annealed Malleable Iron and Hard Bronze, etc. It also can be used as refractory materials.
