Friction pairs, rings, bushings, and abutments of ultrahard materials are made for high-temperature, aggressive and abrasive mediums. High solidity of the materials helps to minimize wearing of the friction unit and to increase reliability and working resource of various devices and their parts.

The friction pairs, rings, bushings, and abutments made of carbide-graphite materials and carbide ceramics can be applied almost in all spheres of national economy: motor, oil, petrochemical, oil and gas refining, nuclear, power, food, and chemical industry. These materials are mainly used in different types of seals and sliding bearings.

Physical properties of carbide-graphite composites
Density, g/cm3 2.8-3.2
Ultimate bending strength, MPa 250-350
Coefficient of compression elasticity, GPa 300-340
Coefficient of thermal expansion at the temperature 20-1000ºC 10-6ºC 3.6-4.2
Coefficient of heat conduction at 100ºC, Wt/m*K 75-200
Solidity HRC 89-92
Working temperature, ºC to 1500
