| Abstract: | In this study, Cu-3.0Ni-0.64Si alloy of different contents of Rare-earth element Ce, which are studied the processing technics and property. The best processing technics show that： As for as Cu-3.0Ni-0.64Si alloy concerned, the temperature of hot rolling is 900℃, time is 60 minutes. The temperature of solution is 900℃, time is 60 minutes. Then by about 80% cold deforming for aging, aging temperature is 480℃, time is 210 minutes. The best combination property for this Cu-3.0Ni-0.64Si alloy is 0.06 wt%Ce of accession ：Conductivity is 48.9%IACS, tensile strength is 733.17MPa. |
