Summary

In the paper, Nb(3)Al wire processing technologies are summarized, and the properties of Nb(3)Al strands made by the jelly-roll process are described. The jelly-roll process was suitable to develop copper-stabilized multifilamentary composites. For the high-energy physics applications, a Rutherford-type cable conductor was developed. For the fusion reactor application, a chrome-plated strand with a critical current density performance of at least 600 A/mm2 at 402 K and 12 T was developed, and 230 km strands, the world's first mass-produced Nb(3)Al wire, were fabricated for the Insert Coil of ITER/EDA.
