Method of producing a superconducting wire/tape comprising the steps of placing a precursor powder in an Ag or Ag-alloyed tube to form a preform, drawing the preform into a wire, and surrounding the finished wire/tape by a nickel layer. One advantage of completely or partly using a nickel layer instead of a silver layer is that a nickel layer is stronger and thus may be made thinner than a silver layer. As a result the total thickness of the metal layer is reduced. Additionally, nickel is lower in cost than silver. The nickel layer may for instance have a thickness of 0.1 mm. |
