ABSTRACT:
A superconductor including V.sub.3 Ga is produced by making a composite of a vanadium core metal, a continuous portion of aluminum surrounding the vanadium core metal or forming a second core, and a copper, silver or copper-silver alloy containing gallium, fabricating the composite to the desired shape, and heat-treating the shaped composite. The vanadium core may contain titanium, zirconium or hafnium, and the continuous portion of aluminum may contain copper or zirconium.
