The resistivity and mechanical properties of Cu–Sn alloys with different compositions were explored by casting, normalising, cold work and subsequent annealing treatment. Results indicated that the Cu–Sn alloy had the characteristics of ultrahigh electrical conductivity, when the Sn content was ∼0·5 wt-. Note that the resistivity of the as cast and annealed Cu–0·5 wt-Sn alloys is 1·55 and 1·26 μΩ cm respectively.
