Abstract:
1. A superconducting wire, the wire comprising: NbTi superconducting material; and a multiplicity of hexagonal elements, wherein, as seen in cross-section perpendicular to a longitudinal direction of the superconducting wire, said elements have a substantially hexagonal outer contour and at least a portion of said hexagonal elements is constituted as Cu—Al composite elements, wherein cross-sections of said Cu—Al composite elements each extend perpendicular to said longitudinal direction of the superconducting wire, said Cu—Al composite elements having an Al core and a Cu sheath that surrounds said Al core, wherein each Cu—Al composite element consists of 10-20% by volume of Cu, or of an alloy containing Cu, and 80-90% by volume of Al.
