Data from Kittel, Introduction to Solid State Physics, 7th Ed., Ch 12
*Superconducting only in thin films or under high pressure in a crystal modification not normally stable. Critical temperatures for those elements from Myers, Ch 13.

It is notable that in the range of data covered by this table, the best conductors like Cu do not become superconducting at all. Neither the noble metals or the magnetic materials become superconducting. That is not to be taken as a statement that they cannot be made superconducting, it is just that the transitions to superconductivity must be at such low temperatures and require such great purity of material that they have not been demonstrated conclusively.
