Improvement in strength and electrical conductivity of Cu–Ni–Si alloys by aging and cold rolling

In order to find the optimum conditions to obtain copper–nickel–silicon (Cu–Ni–Si) alloys with high strength and high electrical conductivity, the aging characteristics of micro-Vickers hardness and electrical resistivity of different Cu–Ni–Si alloys were systematically measured at room temperature. The alloys were isochronally or isothermally aged after solution treatment. The effects of cold rolling after solution treatment as well as the...
