Mechanical properties of two Cu alloys (electrolytic and fire refined) severely deformed by equal channel angular pressing (ECAP) process were investigated. They were treated with a annealing heat treatment to 600°C during 30 minutes and then they were extruded in a Φ=90º ECAP die at room temperature following route Bc. Heavy deformation was introduced in the samples after a considerable number of ECAP passes from 1, 2, 3, 4, 5, 6, 7, 8, to 16. The principal changes were introduced in the first pass by ECAP but a gradual increment in the mechanical properties was observed for the consecutive ECAP passes. Also, the electrical conductivity decreased with increasing numbers of ECAP passes.
