Abstract
The present invention provides an Nb-Ti alloy type superconducting wire having a superconducting filament including a member made of Nb-Ti alloy and a pinning member made of Nb or Nb alloy having no superconducting properties under operating magnetic field, the Nb-Ti based alloy containing Ti in a content of 48 to 65% by weight and the superconducting filament containing Nb or an Nb alloy (A) in a ratio of 20 to 35% by volume. The present invention further provides an Nb-Ti alloy type superconducting wire having a superconducting filament including a member made of Nb-Ti alloy and a pinning member made of Ti or Ti alloy having a critical temperature lower than that of the Nb-Ti alloy and/or having no superconducting properties; the Nb-Ti based alloy containing Ti in a content of 25 to 45% by weight and the superconducting filament containing Ti or a Ti alloy in a ratio of 20 to 35% by volume.
