Two copper alloys are provided. The first copper alloy may have a composition in the range of from 0.2 to 0.6 wt % chromium, from 0.005 to 0.25 wt % silver, and the balance copper. The second copper alloy may have a composition in the range of from 0.2 to 0.6 wt % chromium, from 0.01 to 0.12 wt % magnesium, and the balance copper. The copper alloys of the present invention may also include zirconium to provide additional softening resistance. These copper alloys can easily be drawn or rolled to fine and ultra fine sizes (0.010 inch and smaller) to be used as a single end wire and constructions made therefrom.
