Abstract

The invention relates an Al-stabilized superconducting wire for use in a superconducting magnet used in a charging magnetic field, such as a pulse magnet and the like, and particularly to an Al-stabilized superconducting wire having the properties of reduced size and light weight, high current density, high stability, low AC loss, etc., and a method for producing the same. The said Al-stabilized superconducting wire has a core chosen from a superconducting elementary wire, an electrically insulated Cu or a Cu alloy, or a nonmagnetic metal or alloys thereof, and wherein the superconducting elementary wires and high purity Al wires are alternately stranded around said core. The stranded cable is bonded by impregnating it with solder, or further by subjecting it to a reduction process and heat treatment thereby making it possible to obtain an aluminum stabilized superconducting wire having said high properties.
