Carbon-graphite
These materials have a fine or very fine particle size and can have a very high degree of anisotropy due the axial process. They are made of amorphous carbon and graphite. These materials are designed with specific properties in terms of tribology and electricity which can be reinforced through impregnations with resins or phosphates.
Applications
- Sealing gaskets
- Gaskets
- Bearings
Principales characteristics
- Excellent resistance to corrosion
- Anti-wear
- Long-term stability
- Custom properties
We stock 3 references of carbo-graphite: EK24, EK2240 and EK305.
