The synthesis of nanostructured materials was pioneered by the inert gas condensation and compaction technique. We investigate magnetron sputtering as an alternative processing route in comparison with thermal evaporation. We have studied the elaboration process and alloy formation by annealing as a function of molybdenum content. The sputtered material was investigated by means of X‐ray diffraction, scanning electron microscopy, electron dispersion spectroscopy, atomic force microscopy and Vickers hardness tester. The results indicate that Cu/Mo alloys are semi‐hard nanostructures with colors that change from black to yellow‐golden when the Mo content increases. Hard nanostructured composite alloys were obtained at 500 °C only at high Mo content. The yellow‐golden alloys can be considered as molybdenum bronzes and can be used for integrated circuits (IC), electrical contacts, metallic resistors and high voltage sockets.
