【発明の名称】アルミニウム安定化超電導線
Document Type and Number:
Japanese Patent JP2997121
Kind Code:
B2
Abstract:
PURPOSE:To improve the thermal and electrical stability and provide sufficient mechanical strength against the generated electromagnetic force when used for a magnet by covering the outer surface of a superconductive wire with an aluminum stabilizing member having predetermined characteristics. CONSTITUTION:An aluminum stabilizing member 12 is soldered to a multicore Cu/NbTi superconducting wire 11 so as to be combined. The member 12 is also soldered to a stranded wire 13 of the Cu/NbTi superconductive wire so as to be combined, furthermore the combination is placed in a copper stabilizing member 14 of approximately U-shaped in cross section and is soldered thereto, and a copper stabilizing member 15 of plate-shape is soldered and mounted on an exposed part of the member 12. The aluminum stabilizing member 12 covering the circumference of the superconducting wire, such that superconducting filaments are embeded in a copper matrix, is selected such that its 0.2% yield strength at very low temperatures being not less than 4kg/mm<2>. The residual resistance ratio is selected to be 250 or more, and elements selected from the group consisting of Zn, Si, Ag, etc., of selected value are added in the remainder aluminum alloy. Thereby mechanical strength, as well as thermal and electrical stability, can be enhanced.
