ABSTRACT:
A process for producing a Nb.sub.3 Sn superconducting wire, which comprises preparing a composite from a copper alloy material containing 0.1 to 5 atomic percent in total of at least one element of Group IV of the periodic table selected from titanium, zirconium and hafnium, a tin material and a niobium material, processing the composite into a wire, tape or tube, and heat-treating the processed composite at a temperature of 400.degree. to 900.degree. C. to form a Nb.sub.3 Sn compound.
