Abstract
A composite superconductor comprises a matrix of an alloy which is normally conductive at operating temperatures with the alloy being copper and another alloying element. Several superconducting filaments are embedded in the matrix with these filaments being formed by a diffusion reaction between at least two elements. An aluminum jacket surrounds the matrix. A barrier layer formed from at least one intermetallic copper-aluminum compound is disposed between the aluminum jacket and the alloy matrix. The aluminum jacket may be formed by extrusion at an elevated temperature with the boundary layer between the aluminum jacket and the alloy matrix being concurrently formed by diffusion.
