Niobium-Titanium

Niobium-titanium is the most frequently employed alloy for superconductors. It is also used in medical diagnostics, for example in Magnetic Resonance Imaging tomography. With MRI, cross-sectional images of the body can be made which often permit outstanding clinical assessment of the organs and many pathological organ changes. MRI employs magnetic fields, not x-rays. Magnets of niobium-titanium generate extremely strong magnetic fields when cooled to temperatures near absolute zero. They act as superconductors; current flows without resistance.
