Multifilamentary superconducting Nb-Al composites were produced using powder processing with high overall critical currents J/sub c/ at high magnetic fields. A Nb--3 wt. % Al composite, reacted at 800 /sup 0/C for 16 h, had J/sub c/ >10/sup 4/ A/cm/sup 2/ at 14 T at 4.2 K. J/sub c/ was almost independent of strain for strains up to 1.3%.
