Abstract
A superconducting wire (12), containing NbTi superconducting material and Cu, comprising a multiplicity of hexagonal elements, which, as seen in cross-section perpendicular to the longitudinal direction of the superconducting wire (12), have an at least approximately hexagonal outside contour is characterized in that at least a portion of the hexagonal elements is constituted as Cu—Al composite elements (3), wherein, in cross-section perpendicular to the longitudinal direction of the superconducting wire (12), the Cu—Al composite elements (3) are each constituted with an Al core (4) and a Cu sheath (5) that surrounds the Al core (4). The NbTi superconducting wire is thereby stabilized and has low weight as well as a reduced risk of crack formation during manufacturing, especially during wire drawing.
