Superconducting Cu-Nb-Sn multifilamentary composites are fabricated inexpensively on a laboratory scale. Small (40 ..mu..m) particles of Cu and Nb are compacted, placed in a suitable external jacket for containment, then elongated at room temperature to form a multifilamentary circular wire. Processing yields a multifilamentary Cu-Nb-Sn superconductor with high overall critical current densities J/sub c/ at high magnetic fields. Measurements of the mechanical properties show no degradation of J/sub c/ for strains greater than 1% for composite made with a large areal reduction ratio.
