Product Description

  

Carbon graphite is used as a soft material in a wide range of applications, from wet running to dry running. It provides: · Excellent natural lubricity · Good thermal conductivity · Outstanding thermal shock resistance · Good corrosion resistance Mechanical carbon has been developed in different grades to meet various service conditions: · Resin bonded carbon - an economical, pressed to size material for large volume requirements. · Resin impregnated carbon - Furan resin, Phenolic resin, or Epoxy resin are used as filler to decrease the porosity of carbon. · Metal impregnated carbon - Antimony, Copper, or Babbitt alloys are used as filler for applications requiring higher working temperatures or higher strength.
