- Conventional superconductor
Critical temperatures of some simple metals:
Element Tc (K) Al 1.20 Hg 4.15 Mo 0.92 Nb 9.26 Pb 7.19 Ta 4.48 Ti 0.39 V 5.30 Zn 0.88
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.
