Zheng Yong high temperature resistant, corrosion resistant silicon nitride parts have very high corrosion resistance and heat shock performance, has a wide range of applications in metallurgy low-pressure casting industry. In the aluminum casting industry, the products such as the riser tube and the protective tube have excellent self-lubricity, corrosion resistance, low thermal expansion coefficient and good thermal shock resistance. It is an ideal material for metallurgy low-pressure casting industry because of its good thermal shock stability and non-wetting with aluminum molten solution.
