Abstract
The material characteristics of Cu-Si alloy as a new matrix material for AC superconducting wires are presented. The successful trial fabrication of submicron-diameter Nb-Ti multifilamentary wires with Cu-2.5 wt.% Si alloy matrix is described. The wires, which had filament diameters down to 0.1 mu m, showed high enough critical current density and low AC loss compared to Nb-Ti AC superconductors with a Cu-Ni alloy matrix.<>
