Abstract :
Submicron size ultrafine Cu-Nb-Sn superconducting wire has been fabricated by the powder metallurgy process simulating large scale industrial fabrication using the bundling technique. Starting copper and niobium powders ranged from 250 to 500 μm. Both external and tin core processed wires were fabricated with overall current densities of

A/cm
2at 14 T, demonstrating that both particle size and billet can be scaled up to large scale fabrication.
