context_page_description: Niobium–tin is an intermetallic compound of niobium and tin, used industrially as a type II superconductor.
  This intermetallic compound has a simple structure: A3B. It is more expensive than niobium-titanium, but remains superconducting up to a magnetic flux density of 30 teslas [T], compared to a limit of roughly 15 T for NbTi.
  Nb₃Sn was discovered to be a superconductor in 1954. The material's ability to support high currents and magnetic fields was discovered in 1961 and started the era of large-scale applications of superconductivity.
  The critical temperature is 18.3 kelvins. Application temperatures are commonly around 4.2 K, the boiling point of liquid helium at atmospheric pressure.
  In April 2008 a record non-copper current density was claimed of 2,643 A mm⁻² at 12 T and 4.2 K.
