■ Introduction:
Customized sintered Silicon carbide seal ring parts use high purity silicon powder and graphite powder as raw materials, through sintering. The seal ring has excellent wear resistance, corrosion resistance, high temperature stability and mechanical strength, and can be used in a variety of seal applications requiring high strength, high temperature and high corrosion, such as chemical, petroleum, aviation, aerospace and automotive fields.
