Title: Manufacture of aluminum-stabilized superconducting wire
Inventor: KOSUGI KEIZO
IPC: H01B12/10
Filed: 1992-09-30
Abstract: PURPOSE:To enhance the strength of an aluminum-stabilized superconducting wire without deteriorating superconducting characteristics so as to use the wire as a conductor for a large magnet by performing surface reducing work with the ratio of dimensional change held within 3% and the thickness decreased. CONSTITUTION:An aluminum-stabilized superconducting wire 4 is formed by providing an aluminum stabilizer 4 to cover the outer periphery of a superconducting stranded wire 2 comprising a plurality of superconducting wires 1 each comprising a superconducting filament embedded in a copper matrix. In this case, a material 4 obtained by extruding a material 3 to cover the wire 2 comprising the wires 1 twisted in two lines is subjected to a surface reducing process with the rate of dimensional change in width held within 3% and the thickness decreased. In addition to high purity aluminum, an aluminum alloy formed of high purity aluminum with trace amounts of elements such as Zn, Si, Ag and Cu therein is used as the material 3. The strength of the superconducting wire is thus enhanced without deteriorating superconducting characteristics such as critical current density (Jc), and can be used as a conductor for a large magnet.
