There is a need for high‐strength and highly‐conducting materials for applications such as pulsed high magnetic field coils. Two different approaches were studied in order to strengthen copper‐based conductor materials. On the one hand, microcomposite Cu‐Ag alloys yield high strength as a consequence of their nanoscale microstructure and, on the other hand, a Cu‐based macrocomposite can be strengthened by the use of a steel jacket. In both cases the increase of strength coincides with a decrease of conductivity. Thus, the ideal material balances between these two competing properties.
