Abstract
A multifilamentary superconductor having a large number of NbTi filaments in an aluminum alloy matrix which is stabilized by a high-purity aluminum sheath is disclosed, together with the method of its manufacture. An Al alloy billet having a number of NbTi rods disposed therein is extruded. A superpure Al sheath is added; this product is then enclosed in copper and wiredrawn after which the copper is etched off.
Claims1
A composite superconductor comprising a plurality of superconductive filaments symmetrically dispersed in a matrix of aluminum alloy having substantially the electrical and thermal conductivity and the mechanical properties of an alloy of at least 99.00% Al and 0.05-0.20% Cu, said matrix being in intimate contact with a surrounding stabilizing sheath of aluminum of nominal 99.999% purity.
