| Definition: | production process of Nb3Sn superconducting wires in which islands or filaments of Sn or Sn alloy are coprocessed with Nb filaments in a copper matrix
Note 1 to entry: At its final size, the wire is heated, allowing Sn to diffuse throughout the copper matrix, forming Nb3Sn at the Nb filament interfaces. Note 2 to entry: This entry was numbered 815-14-19 in IEC 60050-815:2015.
