Abstract
The centers of a plurality of copper tubes are filled with an alloy of tin with a minor amount of aluminum and drawn to form Cu-Sn wires which are cabled around a core Nb wire; a plurality of these strands are provided in a copper tube, or a copper foil or finely wound copper wire and drawn to produce a multifilament wire; heat treatment is applied to cause the tin to diffuse and form the intermetalic Nb.sub.3 Sn at the surface of the Nb filaments to produce the ultimate superconducting wire product. The addition of a small quantity of Al to the Sn facilitates processing and improves the final product properties.
