What is the metal used for most electrical wiring and water pipes? Copper is the most common metal used in electrical wires because it has a structure which includes freely-moving negatively-charged particles-called electrons-which are es â¦ sential for the conduction of electricity.
If the plumbing in your home is old, it is likely that your water pipes are made from iron, steel, or lead. Modern water pipes are almost always made from copper, although plastic or polyvinyl chloride (PVC) pipes are becoming popular too.
