Abstract: There are many research reports on the process and mechanism of Cu-Cr-Zr alloy. How to break through the comprehensive performance limit of materials and make them meet the application in complex environment has become a new problem. In the optimization of Cu-Cr-Zr alloy system, adding alloying elements to improve microalloying is the most effective method and the easiest direction of industrialization. After investigating the latest research on adding alloy elements by scholars in China and abroad, most of the tests did not achieve the purpose of improving comprehensive properties, but also made some useful conclusions. To sum up, the scheme of adding multiple alloying elements to comprehensively improve the properties of the alloy is better than that of one or two elements. If appropriate deformation processing and heat treatment processes are matched, the comprehensive properties of "double 70" (conductivity ≥70 % IACS and tensile strength ≥700 MPa) can be easily obtained. This paper summarizes the research progress of adding two and more elements to improve the properties of Cu-Cr-Zr alloy, puts forward the problems existing in the current research, and finally prospects the process and new manufacturing methods in the next study.
