Abstract
A new manufacturing process of the Nb//3Sn superconductor was developed by assembling and co-drawing the Al//2O//3 dispersion strengthened copper, which we found to be suitable for the reinforcing stabilizer of unreacted multifilamentary Nb//3Sn superconducting wires. This composite conductor can be annealed to form the Nb//3Sn layers. Residual resistivity ratio (RRR) of 0. 8 wt. % Al//2O//3-copper alloy was approximately 50 after annealing at 700 degree C for 100 hours. This alloy can be used for the stabilizer of the Nb//3Sn superconductor. The 0. 2 % proof stress was 11 kg/mm**2 after the annealing. Further improvements in the mechanical properties after long time annealing at high temperature are under way.
