Abstract
An aluminum-stabilized superconducting wire includes a superconducting wire member obtained by burying a superconducting filament in a copper matrix and an aluminum stabilizing member covered in an outer surface of the superconducting wire member, and the aluminum stabilizing member is constituted by an aluminum alloy having a 0.2 % proof resistivity of 4 kg/mm.sup.2 or more at a very low temperature and a residual resistance ratio of 250 or more. It is preferable that the aluminum alloy contains at least one element selected from 50 to 1,000 ppm of Zn, 50 to 150 ppm of Si, 50 to 400 ppm of Ag, 50 to 300 ppm of Cu, and 30 to 2,000 ppm of Ce, and that a balance is constituted by Al and an inevitable impurity.
