A new class of ductile superconductors has been prepared by casting and appropriate heat treatments. These alloys superconduct between 4° and 18°K and contain at least 90 atom percent copper and a superconducting phase such as Nb3Sn or niobium. They can be processed into wires by conventional metallurgical techniques.
