Abstract
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.
