Copper is still the most effective conductor of electricity . Combined with its malleability , resistance to corrosion and ability to endure tensile stress , copper is the ideal metal for electrical wiring . Busbars , conductors that distribute power , transformers and motor windings are all dependent upon copper ’ s conductivity , which can be up to 99.75 % efficient . Electrical applications ranging from computers and televisions to mobile phones and portable devices have become major consumers of the copper needed for microchips , circuit boards , electrical connectors , semiconductors , electromagnets , heat sinks and more .
