Niobium alloy

Niobium-tin and Niobium-titanium are essential alloys for the industrial use of superconductors, since they remain superconducting in high magnetic fields (30 T for Nb3Sn, 15 T for NbTi); there are 1200 tons of NbTi in the magnets of the Large Hadron Collider, whilst Nb3Sn is used in the windings of almost all hospital MRI machines.

Niobium-titanium alloy, of the same composition as the superconducting one, is used for rivets in the aerospace industry; it is easier to form than CP titanium, and stronger at elevated (> 300°C) temperatures.

[1][2] C-103, which is 89% Nb, 10% Hf and 1% Ti, is used for the rocket nozzle of the Apollo service module and the Merlin vacuum[3] engines; it is regarded as a medium-strength alloy.

[5] Due to its corrosion resistance and high thermal efficiency, C103 helps reduce material waste and environmental pollution.

Nb-Hf-Ti is an alloy powder consisting of niobium (Nb), hafnium (Hf), and a small amount of titanium (Ti) provides high strength, ductility, high-temperature stability, and remarkable corrosion resistance.
