Copper and Aluminum are the metals that are commonly used in electrical wire. Copper has very good electrical conductivity. Although they are not the best conductors, they are abundant and low cost. Moreover, Gold is also used because it is corrosion resistant.

Copper is usually the ones used for electrical wiring because copper has a great conductivity of electricity and is cheap. They also use aluminum though it is not as conductive compared to copper. Silver is a better conductor than copper but pricey so silver is often used as a coating.
