A method for producing an aluminum-stabilized superconducting wire is dislcosed herein, which comprises alternately winding superconducting elementary wires and high purity wires around a core, such as an electrically insulated copper wire core, impregnating the entire wire arrangement with solder to bind the wires together and subsequently forming or drawing the wire arrangement to increase the adhesion between the wires. In another embodiment, the thus-impregnated wire arrangement is subjected to a heat treatment to recover the residual resistance ratio of the aluminum. The impregnated wire arrangement is characterized by having a high mechanical toughness and improved electrical contact for greater electrical stability.
A method for producing an Al-stabilized superconducting wire comprising a superconducting elementary wire and a high purity aluminum wire alternately wound around a core, said method comprising alternately winding a superconducting elementary wire and a high purity aluminum wire around a core so that said superconducting elementary wire and high purity aluminum wire are in contact with each other, said core being selected from the group consisting of a superconducting elementary wire, an electrically insulated copper wire, an electrically insulated copper alloy wire, a nonmagnetic metal wire and a nonmagnetic metal alloy core, said aluminum wire serving as a stabilizer in said wire arrangement;
