Carbon Graphite has the good property of good resistant-corrosion, high thermal conductivity and lower friction, good self-lubrication, the smaller expansion. They can be made into the seal faces, bearings and so on. It is ideal to choose it as the frictional mating rings.
It has property of excellent resistant-corrosion, high mechanical strength, and high thermal conductivity, good self-lubrication, used as seal faces, bearings and tubes in Food Industry, aviation, aircraft, machinery, metallurgy, printing and dyeing, pharmaceutical, auto industry and so on. When the sic faces are combined with graphite faces the friction is the smallest and they can be made into mechanical seals which are able to work in highest working requirements.
Tungsten carbide is widely used as seal faces with resistant-wearing, high fractural strength, high thermal conductivity and small heat expansion co-efficient. It is the best material to resist heat and fracture in all hard face materials.
Ceramic seal faces, bushes and rings encompass the property of the good sealing, resistant-high-temperature, and resistant-corrosion, resistant-wearing and are generally used in spacecraft, machinery, metallurgy, printing and dyeing, foodstuff, pharmaceutical, auto industry and so on.
