Conductors

Materials that are made up of atoms whose electrons are easily freed are called conductive materials or "conductors". Platinum, gold, and silver are examples of the very best conductors of electricity. Gold is used extensively in small quantities for high-value products like microelectronics, high quality audio components, computer chips and telecommunications satellites.

Copper and aluminum are also quite excellent conductors of electricity and much less expensive. Almost all electrical wiring is aluminum or copper.
