The paper presents the results of experimental research on the evolution of the set of high strength and electrical properties of Cu-Ag (1-7 wt.%) alloys. The research was focused on the modification of the primary as cast structure of Cu-Ag alloys to finally composite filamentary nanostructure by appropriate selection of heat treatment parameters, the amount of cold deformation and their number and sequence. Metallographic analysis for casts, drawn wires and wires after heat treatments was performed with the use of SEM and TEM microscopy presented in the paper. Suitable quantity and process sequence of cold plastic working and heat treatment allows to obtain wires with a tensile strength of 700-1450 MPa (total true strain more than 7) at the simultaneous high electrical conductivity of 68-95 % IACS. The influence of materials microstructure and their value of deformation on the changes in rheological and fatigue properties of wires was also determined.
