Here's why:
* Excellent Conductivity: Copper has exceptionally high electrical conductivity, meaning it allows electricity to flow through it with minimal resistance.
* Abundance and Cost: Copper is relatively abundant and affordable compared to other high-conductivity metals like silver.
* Durability and Workability: Copper is strong, durable, and can be easily drawn into wires or shaped into other forms.
* Resistance to Corrosion: Copper is relatively resistant to corrosion, making it suitable for various environments.
While aluminum is also used as a conductor, especially in high-voltage transmission lines, copper remains the dominant material due to its superior conductivity and versatility.
