The Brazil retains much of niobium reserves in the world, and that most of it is concentrated in Minas Gerais.
Considered one of the rarest materials in the world and more resistant to corrosion, identified as a superconductor whose application is the alloying (mainly steel), its main function is to enable the improvement of a product without affectingr any existing property. The element, even in low amounts, enables an increase of resistance and adhesion, concomitantly, microligante being the most sought for this purpose. In other words, like a touch of magic, only 100 grams mixed in a ton of steel, the alloy becomes malleable and strong.
Brazil does not matter niobium to be self-sufficient to meet domestic market demand, nor exports niobium "in natura", In contrast, niobium may be replaced by titanium, vanadium and tantalum in the superalloy composition.
