1. Copper: Widely used in electrical wiring due to its excellent conductivity and affordability.

2. Silver: The best conductor of electricity, but its high cost limits its use in most applications.

3. Gold: Another excellent conductor, often used in electronics because it resists corrosion.

4. Aluminum: A lightweight and cheaper alternative to copper, often used in electrical wiring and other applications.
