What are the most common metals utilized as conductors?

Copper and aluminum are the most prevalent metals used as conductors due to their excellent electrical conductivity, relatively low cost, and availability. Copper, in particular, is highly favored in electrical wiring because it has a very high conductivity, making it ideal for transferring electrical currents efficiently. Its resistance to corrosion and ease of soldering add to its popularity in various electrical applications.

Aluminum also serves as a significant conductor, especially in overhead power lines and applications where weight is a concern. It is lighter and less expensive than copper, which makes it suitable for large-scale electrical infrastructures. While other metals like gold and silver have high conductivity, they are often too costly for widespread use in electrical applications.

The other metals listed, such as iron and steel, are not optimal for electrical conduction due to their higher resistivity compared to copper and aluminum, which can lead to more energy loss in the form of heat. Zinc and nickel, while useful in other applications, similarly do not match the conductivity levels required for effective electrical conduction, further solidifying the position of copper and aluminum as the most commonly utilized metals for this purpose.
