Niobium and vanadium are type-II superconductors, while most other superconducting Element s are type-I materials. Almost all compound and alloy superconductors are type-II materials.

The most commonly used conventional superconductor in applications is a Niobium - Titanium alloy - this is a type-II superconductor with a ''Tc'' of 11 K. The highest critical temperature so far achieved in a conventional superconductor was 39 K (-234 °C ) in Magnesium Diboride .
