Silver in the pores of graphite materials enhances electrical conductivity by a factor of 2 to 3 when compared to copper graphite compounds. Silver graphite compounds can either be produced by pressing of powder mixtures or (for a lower silver content) impregnation of a porous graphite with liquid silver salts, which can be reduced within the pores of the graphite to metallic silver subsequently. Furthermore, an impregnation with a silver melt can be used but is complicated by the high toxicity.

Due to the high cost of the raw material, use of silver graphite compounds is confined to sophisticated applications involving high current densities and for the transmission of low currents and voltages where low transmission resistance is involved. Typical applications include carbon brushes in wind turbine generators, silver graphite brushes for signal transmission in tacho generators or aerospace applications and for measuring current transmission and collectors in wire winding machines.
