Niobium's atomic number is 41 and its symbol is Nb. Niobium is a ductile transition metal that used to be known as “columbium” until 1949. About 65% of all niobium is produced in Brazil, with the majority of niobium being used to produce steel. Niobium is also used in medical devices and jewelry because some alloys are physiologically inert and perfectly hypoallergenic. Niobium is also desirable for jewelry because it produces a wide array of vibrant colors when anodized.
