Superconductivity in MgB2 and Alloys

Using CuNb alloys cast at Airco and at Ames Laboratory, processes have been developed for drawing commercially useable lengths of wire and for electroplating the strands with high purity tin. Tensile strengths exceeding 1378 MPa have been observed during the cold drawing operations. Critical current densities were measured in fields of 1.0 to 10 Tesla. J c values taken at 8 Tesla, for example are 812 A/mm 2 for 20% Nb 0.15 mm diameter wire, and 997 A/mm 2 for 30% Nb 0.30 mm diameter wire.
