Carbon Graphite materials are a composite of different carbon materials and inorganic additives which have exemplary performance in demanding applications in either wet or dry applications. Carbon Graphite Materials are preferred for many different applications because of their unique combination of characteristics:
- Low Wear and Coefficient of Friction for Tribological Applications
- High Thermal Conductivity
- Low Coefficient of Thermal Expansion
- Low Electrical Resistivity (or High Electrical Conductivity)
- High Strength at High Temperatures
- Chemical Resistance
- Oxidation Resistance
- High Young’s Modulus
- Relatively Inexpensive
Carbon Graphite materials are porous as produced and are often impregnated or have a coating applied to impart additional characteristics such as imperviousness, increased strength, and Thermal Conductivity.
Impregnants include: Resins, Antimony, Copper, Silver, Babbitt, Bronze and other Inorganic materials
Common Coatings include: TeflonTM, Pyrolytic Carbon or Pyrolitic Graphite, Silicon Carbide, Diamond Like and Diamond Coatings
