FWIW, most all salts contain a metal: sodium chloride, epsom salt (magnesium sulfate), calcium chloride, potassium nitrate, etc.
Liquid sodium was used in early nuclear sub reactors as a cooling
agent because of its excellent thermal conductivity. It turns out that liquid sodium is a better conductor of heat than mercury
(also a decent electrical
conductor), and replaced the mercury
that was used in early reactors... I'm not sure what the most recent subs use - too lazy to google
