Copper is the preferred metal for electrical wiring primarily because of its excellent electrical conductivity. This means it allows electric current to flow through it with very little resistance, minimizing energy loss as heat. Another important property is its ductility. Ductility refers to the ability of a metal to be drawn into a wire without breaking. Copper's high ductility allows it to be easily drawn into thin wires, making it practical for wiring applications. While other metals might be conductive, copper's combination of high conductivity and ductility makes it the most efficient and practical choice for electrical wiring.
