| Abstract: | Cu-Si-Ni and Cu-Si-Ni-Ce were prepared in a non-vacuum induction furnace.The properties of the two alloys were studied with the effect of trace cerium on the properties of the Cu-Si-Ni alloy studied in terms of microhardness and electric conductivity.It is found out that trace cerium has little effect on the electric conductivity but can refine its microstructure effectively. |

| Keywords: | rare earth Cu-Si-Ni microhardness electric conductivity |
