Nanocomposite wires having conductivities higher than for metal wires were prepared by pulling tows from a supported array of multiwalled carbon nanotubes and sputter depositing metal on the tows, which resulted in transverse bridges between adjacent nanotubes in the tows. These transverse bridges of metal attached adjacent nanotubes to each other and provided paths for electricity to flow from one nanotube to another.
