SiC Metallurgical Grade Description: Metallurgical grade Silicon Carbide is mainly used in Iron foundries for electric furnace production of grey, ductile, and malleable iron.

Cutting tool materials - Coromant

Silicon nitride grades are successful in gray cast iron, but a lack of chemical stability limits their use in other workpiece materials. Sialon (SiAlON) grades coine the strength of a self-reinforced silicon nitride network with enhanced chemical stability. Sialon grades are ideal for machining heat resistant super alloys (HRSA).
