No electrical engineering without conductors!

 Hundreds of specialized metal alloys exist just for "wires" because besides σ, 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, ...);
• Resistors;
• Heating elements; ...
• Transparent conductors
