Superconducting Niobium-Titanium Alloys

Niobium titanium alloys are used as a type II superconductor wire for superconducting magnets.  Applications of these superconducting magnets include magnetic resonance imaging and nuclear magnetic resonance instruments, and in particle accelerators.

The alloys are generally available with 47%, 50%, and 55% titanium.
