| Abstract: | In the paper,following a review of the history of Cu-Ni-Si lead-frame material, the strengthening mechanism of Cu-Ni-Si alloy has been elaborated. While ageing strengthening is the main strengthening method of the alloy, strain strengthening and solution strengthening affect the performances of the alloy to some extent. Besides, the correlations have been analyzed between the performance of the alloy and the weight ratio of Ni and Si and the type and amount of added alloy elements such as P, Fe, Mg, Zn and Cr that enhance the performance of Cu-Ni-Si alloy. Cu-Ni-Si alloy is a promising lead-frame material with its strength about 600-860 MPa and its conductivity 30-60 %IACS. |
