Metal Impregnated Carbon Graphite

Carbon-Graphite and graphite materials become porous after processing. Therefore, it is typical to impregnate them with resin or metals to enhance strength, thermal conductivity, reduce resistivity, and minimize porosity. Various metals are used for specific benefits; for instance, antimony enhances friction and wear resistance. Metal impregnation allows the material to withstand higher temperatures and pressures compared to resin impregnation
