It was not until the early 20th century that niobium was first used commercially. Brazil is the leading producer of niobium and ferroniobium, an alloy of niobium and iron. Niobium is used mostly in alloys, the largest part in special steel such as that used in gas pipelines.Although these alloys contain a maximum of 0.1%, the small percentage of niobium enhances the strength of the steel.t was not until the early 20th century that niobium was first used commercially.
