Description/Abstract In order to fabricate a large-bore, high-field magnet which achieves a low coil weight and volume, a high strength compound superconducting wire is required. The alumina-copper strengthened (Nb,Ti){sub 3}Sn wire which contained 30 vol.% alumina-Cu alloy fabricated by using the tube process has been developed and tested for critical current density, mechanical properties, transverse compressive stress effects and related properties. As a result, it was found that the reinforced (Nb,Ti){sub 3}Sn wire had high transverse compressive stress tolerance, for example only 3% decrease which was 1/3 of the Cu matrix wire in I{sub c}I{sub c0} at 60 MPa and reversibility in I{sub c} between 0 and 200 MPa. Using the newly developed reinforced-(Nb,Ti){sub 3}Sn wire, it will be possible to fabricate a lightweight, large-bore, high-field and compact superconducting magnet in the near future.
