Widely used in various fields including water pumps for automobiles, chemical industry, petroleum, metallurgy, ore dressing, paper pulp or dealing, mixing machinery and refrigeration compressors and etc.
They have the property of excellent resistant-corrosion, high mechanical strength, high thermal conductivity, good self-lubrication, used as seal faces, bearings and tubes in spacecraft, machinery, metallurgy, printing and dyeing, foodstuff, auto industry industry, phamaceutical 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 the highest working requirements.
