Copper is a conducting material, not a semiconducting one. It's perhaps the most
widely used conductor because it offers the best combination of low resistivity and
low cost.
It is too expensive, too heavy and not a suitable material for most applications.
Regular copper wires have an electrical conductivity of 58.0 MS/m at 20å¡C. Copper is an inexpensive, highly conductive material used in most houses and electronics.
A copper ions has a positive charge, most commonly 2+.
If a material allows free electrons to move easily from one atom to another then we call that material a conductor. Most metals let their free electrons roam, so most metals are good conductors. Silver is the best conductor. Copper is almost as good at conducting as silver, and it costs a lot less, so copper is the most popular material used in electrical pathways, or circuits.
PVC is mostly always a gray material. Most commonly used in piping and vinyl siding it is one of the more commonly used plastics as well as inexpensive. It is a rigid durable and has great impact strength.

A metal roof is roofing material made out of some sort of metal. Most commonly steel but also available in copper, aluminum, and zinc.
Copper is the most commonly used conductor material in wiring, steel is also used but is much firmer and harder to bend.
