Ruihong's silicon nitride ceramics has superior characteristics in mechanical strength, wear resistance and corrosion resistance and they are widely used in industrial machinery and for other applications. Especially silicon nitride is used for high-reliability parts in high temperature and high pressure environment such as automotive parts because of its high mechanical strength and superior heat shock resistance.

As silicon nitride material has superior characteristics in strength at high temperature, heat shock resistance and corrosion resistance, we are confident that our components will help you to produce higher quality products by minimizing eluted contamination and to reduce operation cost by parts with longer life in aluminum foundry equipment such as hot chamber and cold chamber.
