Niobium-titanium alloy superconductors

Niobium-titanium alloy superconductors are the "pioneer materials" of the superconductivity industry. Together with Nb3Sn superconductors, it is the material of choice for practical superconducting magnet applications. It has a high upper critical magnetic field (about 11 T at 4.2 K and 14 T at 2 K), can be drawn well with copper, and has good processability, high strength, and good superconducting properties.
