This paper has made a present situation review of research on high-strength and high-conductivity copper alloys. Several hotspots in this field such as high-strength and high-conductivity copper alloys prepared by rapid solidification, dispersion strengthen copper made with in-situ oxidation and Sol-Gel method, Cu-based in-situ composites, Cu-based lead frame materials and the application of rare-earth in high-strength and high-conductivity copper alloys have been introduced. It is pointed out that the precipitation strengthening and multi-micro-alloying are effective methods to increase the performance of high-strength and high-conductivity copper alloys; the copper based composite is the future development trend; the comprehensive performance and industrialization are pursued in the development of the alloys.
