Silicon Nitride (Si3N4) is a high-performance ceramic, which is used in Aluminium and magnesium castings in the foundry industry. The material is characterised by its excellent chemical resistance to all Aluminium alloys, magnesium alloys, foundry chemicals and caustic soda. Other material characteristics are its very high strength and thermal conductivity.
Because of these properties, Silicon Nitride is suitable for components such as thermocouple protection tubes and riser tubes for low-pressure die casting as well as heating tubes to keep liquid Aluminium at temperature. Further customer-specific components are available on request.
