Metal Impregnated Carbon Graphite

Carbon-Graphite and graphite materials are porous after they are processed. Hence it is common to impregnate these materials with resin or metals to: increase their strength, increase the thermal conductivity, reduce the resistivity, reduce the porosity.

Different types of metals are impregnated for different effects, e.g: antimony is added to improve the friction and wear resistance characteristics of the carbon-graphite compound.

The difference between resin impregnation and metal impregnation one is, with metal-impregnation, the material is able to handle higher temperature and higher-pressure applications.
