People use copper more than wiring because it conducts well and is reliable. Copper prices and the good performance of copper conductors have made copper popular in electrical systems. It is a preferred choice for many uses. According to the CPSC, around two million homes and mobile homes in the US have had aluminum wiring since 1965.
