Niobium (Nb) is a chemical element with atomic number 41. It is a soft, silvery-white metal known for its high resistance to corrosion and excellent strength at high temperatures. Niobium is primarily used in alloys, particularly in steel production, to enhance strength, durability, and resistance to heat. It is also used in superconducting magnets and various electronic components.

Niobium becomes a superconductor, conducting electricity with no resistance at very low temperatures.

It was originally named "columbium" after Christopher Columbus before being renamed niobium in the 1950s.
