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.
3) Copper is resistant to corrosion (it is very unreactive). Uses. 1) Copper is the main metal for electrical wiring (compare with aluminium). 2) Copper is malleable which makes it an ideal material for gas pipes and water pipes.Copper is below hydrogen in the reactivity series and therefore it does not react with water. Copper is the metal used for plumbing in houses.ses. 1) Copper is the main metal for electrical wiring (compare with aluminium). 2) Copper is malleable which makes it an ideal material for gas pipes and water pipes.
