Vanadium–gallium

has an A15 phase, which makes it extremely brittle. One must be extremely cautious not to over-bend the wire when handling it. == Fabrication of superconductive wires or tapes ==

wires can be formed using solid-state precipitation. File:V3GaTape1.jpg| superconducting tape ( cross section).
