Silicon nitrides (Si3N4) feature an excellent combination of material properties. They are nearly as light as silicon carbide (SiC), but their microstructure gives them excellent thermal shock resistance and their high fracture toughness makes them resistant to impacts and shocks. Used at high speeds up to 4,000 sfm in cast iron machining.
Our silicon nitride grade for all irons, especially ductile and nodular irons. An extremely hard, wear-resistant silicon nitride for roughing and finishing at elevated speeds. Works in continuous and interrupted cuts.
