Abstract
In order to get a modified Cu-Ni alloy for electric components with better mechanical properties at high temperature and corrosion resistance, a modified Cu-Ni alloy for electric components was produced by sectional mechanical milling and alloying. The alloy was characterized by OM, SEM and EDS, the mechanical properties and corrosion resistance were tested and analyzed. The results showed that the modified alloy of Cu89.3Ni5Sn5Sr0.5Y0.2 with better mechanical properties and corrosion resistance could be successfully produced by the sectional mechanical milling and alloying. Compared with the existing alloy of Cu90Ni5Sn5, the Cu89.3Ni5Sn5Sr0.5Y0.2 alloy could be featured with better mechanical properties, especially mechanical properties at high temperatures, and corrosion resistance. The tensile strength at the temperatures of 20 ℃, 100℃, 200℃ and 400℃ was increased by 87 MPa, 144 MPa, 211 MPa and 259 MPa, respectively. The corrosion potential of the new alloy moved to positive direction by 438 mV.
