Abstract

Most superconducting wires for low-field (≤8-T) applications are multifilamentary NbTi embedded in an oxygen-free copper matrix. Copper has been selected as the stabilizing matrix not only for its good thermal and electrical properties but also for its mechanical properties which are important in fabrication. Oxygen-free copper has strength compatible with NbTi alloys and good ductility. As a result, the composite, multifilamentary NbTi in a copper matrix, can be fabricated by conventional methods of metal working, i.e., extrusion, wire drawing, and rolling.
