| Abstract: | The influences of mass ratio and content of Ni and Si on the properties of Cu-Ni-Si alloy were reviewed. The reinforced mechanism of Cu-Ni-Si alloy and the factors of influence on it's electrical conductivity were summarized. Adding minor amounts of alloy elements Cr,Zn,P and Al to Cu-Ni-Si alloy as example was discussed. The effects of different heat treatment processes on the properties of Cu-Ni-Si alloy after ageing were introduced. |
