Electric Conductor

Most of the best conductors of electricity are metals. Iron is a good conductor of electricity but not the best. Iron is a metal, which makes it a much better conductor than an insulator, but different metals have different conductivity levels. Iron is a relatively cheap metal and is widely used in products requiring conductance.

Materials are ranked according to their electrical resistivity. A lower electrical resistivity indicates that a material is a better conductor. The best conductors are silver, gold and copper, while titanium and stainless steel are the worst metals; iron falls roughly in the middle of these two groups. As a general rule, elements with a single valence electron are better conductors than those with more. They are able to displace electrons easier to allow the passage of electrons from electricity through the material.
