A composite superconducting wire and a method of manufacturing the wire is disclosed. Nano-particle dispersion strengthened copper is co-drawn with Niobium rod to produce DSC-1Nb wire. n numbers of DSC-1Nb wires are then stacked in a hollow DSC tube and drawn to form a DSC-n.Nb hexagonal wire. In a separate preliminary process, Tin rod is co-deformed with Copper tube to form a Cu-1Sn wire. m DSC-n Nb wires and 1 Cu-1Sn wires are then wrapped by Niobium foil and placed into a Copper tube. This entire assembly is then drawn to a finished size. The drawn composite is then subjected to heat treatment with a final stage at 650-700&#xb0; C. for about 100 hours or longer. The new wire has higher electric critical current and higher mechanical strength than the controlled conventional ones.
