Abstract
The purpose of the present invention is to provide a niobium-aluminum precursor wire having properties such as expression of flexibility and ensuring a large single-wire length, as well as a twisted wire, a superconducting wire, and a superconducting twisted wire formed of the niobium-aluminum precursor wire. The present invention provides a niobium-aluminum precursor wire and a twisted wire using the same, the niobium-aluminum precursor wire including: a rod-like winding core (5) formed of a stabilized copper, or a stabilized copper and an unstabilized copper; a laminated body (3) that is wound around the winding core (5) and that is formed of an aluminum foil and a niobium foil laminated one on the other; and a covering body (1) that covers the circumference of the laminated body and that is formed of a stabilized copper, or a stabilized copper and an unstabilized copper. The volume ratio of the stabilized copper with respect to the unstabilized copper contained in the precursor wire is 0.5-2.0, and the volume ratios of the stabilized copper contained in the winding core (5) and the covering body (1) are within prescribed ranges. According to the present invention, a superconducting wire and a superconducting twisted wire are provided by thermally treating the precursor wire and the twisted wire.
IPC Classes ?
- H01B 12/08 - Stranded or braided wires
- H01F 6/06 - Coils, e.g. winding, insulating, terminating or casing arrangements therefor
