The effects of metallurgical processing on 60 Hz ac losses and dc critical currents in Nb/sub 3/Sn tapes fabricated by the solid state diffusion technique were investigated. An addition to Al to the Cu-Sn alloy for the matrix resulted in large reduction in the ac losses of Nb/sub 3/Sn tapes, but the highest linear critical current densities were observed in Nb/sub 3/Sn tapes produced with a Nb-1 wt % Zr core in a Cu-13 wt % Sn matrix. Values of the losses and the crtical currents in these tapes can meet the present requirements for the ac superconducting power cables.
