A bronze processed multifilamentary Nb3Sn superconducting wire,CuNb/Nb3Sn, with CuNb reinforcing stabilizer, which exhibited a residual resistance ratio of 20 and a magnetoresistance of 0.2 μQ, cm at 23 T and 4.2 K, was newly developed. The yield stress at 4.2 K for CuNb/Nb3Sn was noticeably improved and the value of 22 kg/mm2 was obtained even after the heat-treatment of Nb3Sn formation at 700 -C for 200 hours. The strain effect of Jc for CuNb/Nb3Sn was described well by using the upper critical field in the prestrain state. It was verified that the CuNb/Nb3Sn wire has the performance enough for both mechanical and superconducting properties under an enormous electromagnetic force in high magnetic fields.
