Features:
It is characterized by its high hardness (9 Mohse), good toughness and grinding qualities. 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.
Application:
It also can be used for production of refractory materials and as free grains for blasting.
