The most important niobium application is an alloying
element to fortify high strength, low alloy (HSLA) steels for manufacturing
automobiles and building high pressure gas transmission pipelines.
 Another
major application is to provide creep strength in superalloys that
operate in the hot section of aircraft gas turbine engines.
Among other notable applications are stainless
steel auto exhaust systems and superconducting niobium-titanium
alloys for use in building MRI magnets, as well as electronic ceramics
and camera lenses.
In addition, several developmental applications
are being explored as a technical option for a diverse group of
end users. They include:
- catalysis
- high temperature alloys with low density
- thin films for optical, tribological, and electronic
uses
- electronics
- medical
