In a superconducting magnet using Nb3Sn wire, a strong electromagnetic force called hoop force is generated when the magnetic field becomes higher and the diameter becomes larger, and this electromagnetic force causes a large strain in the wire, resulting in a problem of degradation of superconducting properties．In order to solve this problem, it is necessary to increase the strength of Nb3Sn wire. In this study, we conducted a basic research to evaluate the metallurgical structure and mechanical properties of copper alloys of various compositions to strengthen the copper matrix after superconducting phase formation．
