The interaction of copper with an Nb-33%Zr alloy in the cast state and after vacuum-annealing at 1000° followed by rapid cooling is studied. The solubility of copper in this alloy at 1000° is under 0.3%. Copper present in an Nb-33%Zr in quantities up to 3.6% has practically no effect on the superconducting transformation temperature, and has a positive effect on the critical current.
