|No electrical engineering without conductors! Hundreds of specialized metal alloys exist just for "wires" because besides s, other demands must be met, too:||Money, Chemistry (try Na!), Mechanical and Thermal properties, Compatibility with other materials, Compatibility with production technologies, ...|
|Example for unexpected conductors being "best" compromise:||Poly Si, Silicides, TiN, W in integrated circuits.|
|Don't forget Special Applications:||Contacts (switches, plugs, ...);
Heating elements; ...
