Composite wires in which a noble metal annulus is welded to an electrically-conductive, non-noble metal wire core. Methods of forming the composite wire and semiconductor packaging having at least one lead bonded to the composite wire are also disclosed.

Composite noble metal wire

A multifilamentary superconductor composite having a high fill factor is formed from a plurality of stacked monofilament precursor elements, each of which includes a low density superconductor precursor monofilament. The precursor elements all have substantially the same dimensions and characteristics, and are stacked in a rectilinear configuration and consolidated to provide a multifilamentary precursor composite. The composite is thereafter thermomechanically processed to provide a superconductor composite in which each monofilament is less than about 50 microns thick.

Fine uniform filament superconductors

A superconducting magnetic coil includes a first superconductor formed of an anisotropic superconducting material for providing a low-loss magnetic field characteristic for magnetic fields parallel to the longitudinal axis of the coil and a second superconductor having a low loss magnetic field characteristic for magnetic fields perpendicular to the longitudinal axis of the coil. The first superconductor has a normal state resistivity characteristic conducive for providing current limiting in the event that the superconducting magnetic coil is subjected to a current fault.
