Multifilamentary (Nb,Ti){sub 3}Sn superconducting wires with reinforcing stabilizer of CuNb composite, CuNb/(Nb,Ti){sub 3}Sn, were developed. The outstanding point is that the 0.2% proof stress at 4.2 K in CuNb/(Nb,Ti){sub 3}Sn was extremely improved to 320 MPa even after the heat treatment at 670 C for 192 hours, which is 1.8 times higher than that in ordinary Cu/(Nb,Ti){sub 3}Sn. The overall J{sub c} value in CuNb/ (Nb,Ti){sub 3}Sn was obtained to be 110 A/mm{sup 2} at 16 T and 4.2 K. These results show that the bronze processed multifilamentary (Nb,Ti{sub 3})Sn superconducting wire with CuNb reinforcing stabilizer is actually employable for a high field superconducting magnet.
