New technology is presented in the work for copper wire processing. This technology consists of deforming wire in a rotating equal-channel stepped die and subsequent drawing. The die rotates around the axis of the wire and creates stress due to equal-channel angular broaching and twisting within the die. Results of a laboratory experiment show that after deformation an ultrafine grained graded microstructure with a high content of high-angle grain boundaries is obtained. Tensile strength of deformed copper wire in comparison with undeformed wire increases from 302 to 635 MPa, and yield strength increases from 196 to 406 MPa.
