It is used as an alloying element in steel production in the form of
ferroniobium (Fe-Nb).
Catalao is a Brazilian producer of
ferroniobium, a key element used in the strengthening of steel and for superconductive materials and superalloys, such as in jet engines or MRI scanners.

If increase of titanium content in ferroalloy enables reduction of its density and melting point of the alloy changes insignificantly [8], in melting of ferrovanadium,
ferroniobium and ferromolybdenum sharp increase of temperature of alloys is observed as content of the main alloying element increases, which causes reduction of the pool dimensions and need to reduce optimum mass of the metal being remolten.
Montreal, Quebec SIC: 1060 Sequoia is engaged in mining and production of Niobium,
Ferroniobium and various metallic minerals.
CBMMs production of
ferroniobium was 23,327t last year, compared to 25,006t in 1999, and the expansion would lift capacity from 30,000 t to 45,000t.
