What metal is most commonly used as a conductor?

Copper is the most commonly used metal as a conductor due to its excellent electrical conductivity. Its atomic structure allows electrons to move freely, which facilitates the efficient transfer of electric current. In addition to conductivity, copper is also malleable and ductile, making it easy to draw into wires and shape for various applications in electrical wiring and electronics.

Copper's thermal conductivity is also high, which enhances its performance in heat dissipation for electrical devices. Plus, its resistance to corrosion ensures that it maintains conductive efficiency over time, making it a preferred choice in many industries, including electrical and telecommunications.

While aluminum is also a good conductor and often used in certain applications, copper generally has superior conductivity properties, which is why it is the standard choice for most electrical wiring and components.
