Silican Carbide Bush
Silicon carbide is the ideal sealing material. It has good corrosion resistance, higher mechanical intensity, excellent resisting wear ability and high temperature, good self-lubricity and making-group, low friction factor, good heat-conduction and so on.
Chinatungsten Online can supply silicon carbide bushing as per the clients' specific requirement. Materail: SSiC, RBSiC, /SiC+C, SiC etc. with controlled porosity.
