Selection and use of grinding wheels - EE Publishers

Silicon carbide: This is very sharp and extremely hard, but its use as an abrasive is limited to some extent by its brittleness. Silicon carbide should be used in the grinding of low tensile strength materials such as grey cast-iron, chilled iron, bronze, aluminium, copper, brass and non-metallic materials.
