Abstract:
A method of manufacturing an aluminum-stabilized superconducting wire, comprising the step of hot-extrusion-coating an entirety or a part of an outer circumference of a superconducting wire which includes a superconducting filament embedded in a copper or copper-alloy matrix, with a stabilizer made of a precipitation-type aluminum alloy, wherein the precipitation-type aluminum alloy is an Alâ€”Ni alloy containing 100 to 25000 ppm of Ni, and the stabilizer made of the precipitation-type aluminum alloy is subjected prior to the hot extrusion coating step, to an aging-heat treatment in which it is heated at a temperature of 250Â° C. to 500Â° C. for 10 minutes or more.
