The related link lists all of the elements of the Periodic Table, by electrical conductivity. The top of the list is the worst conductor (Sulfur). The most conductive is silver. The second most conductive metal is copper. Due to expense of silver, copper is preferred. Aluminum is commonly used due to weight factor and cost. (even though a thicker wire is necessary to carry the same current).

Gold, while more expensive and less conductive than copper, is resistant to corrosion, and is very ductile.
