Niobium–titanium

For stronger magnetic fields, higher performance superconductors, such as niobium–tin, are commonly used, but these are more difficult to fabricate and more expensive to produce.

[4] Magnet resonance imaging (MRI) systems, most of which use Nb-Ti, accounted for about 80% of the total market value.

[7] They operate at 4.5 K and generate fields of up to 4.5 T. 1999: The Relativistic Heavy Ion Collider uses 1,740 Nb-Ti SC 3.45 T magnets to bend beams in its 3.8 km double storage ring.

In 2008, a test coil achieved stable operation at 52 kA and 6.4 T.[11] The Wendelstein 7-X stellarator uses Nb-Ti for its magnets, which are cooled to 4 K to create a 3 T field.

It will be deployed for the Chūō Shinkansen, providing passenger service between Tokyo, Nagoya, and Osaka at a planned maximum operating speed of 505 km/h.
