Multifilamentary (Nb, Ti)_3Sn superconducting wires with reinforcing stabilizer of CuNb composite, CuNb/(Nb,Ti)_3SN, were developed. Previously, e researched on the effect of reinforcement of CuNb composite as a CuNb/(Nb, Ti)_3Sn wire and its stability by investigating the MQE (minimum quench energhy). A test coil was fabricated using this reinforced wire without extra reinforcing material. The coil was produced by the "React and Wind method" and "high-tension-winding", then electromagnetic force for the wire was applied by charging electric current in the coil up to 10T. The coil was energized successfully and the generated electromagnetic force for the wire reached 170MPa at 10T without any degradation of test coil. Already, the tension of the coil windings were 110MPa at 4.2K, 0T. Thefore, the maximum force applying to coil windings was 280MPa. These results proved that the bronze processed multifilamentary CuNb/(Nb, Ti)_3Sn had exellent mechanical properties, and a possibility to realize compact design of future superconducting magnet was confirmed.
