Properties of Graphite Material
1.Good lubrication
2. Excellent thermal conductivity
3. Excellent corrosion resistance
4. High resistance to oxidation
5. Higher resistance to thermal and mechanical shocks
6. High mechanical strength and machining accuracy
7. The surface is hard and the bending strength is good
Resin impregnated carbon graphite to improve strength and wear
resistance and reduce material porosity.
Metal-impregnated carbon graphite for added density and high
temperature resistance.
Graphite parts can be widely used in modern industrial equipment,
such as sealing rings of chemical centrifugal pump reactors,
hydroelectric generators and rotary roasters; piston rings and
bushings of compressor oxygen machines and bellows, screen motors
and other types of instruments Bearings; sliding parts of motors,
subway and mine motor brushes, and sliding parts of trolleybuses,
etc.
