Take a look at the chart in the link below. Silver (Ag) is the very best conductor and Copper (Cu) is very close to silver, conducting about 95% as well. Gold (Au) is the third best, conducting about 73% as well as silver. Then comes Aluminum (Al) in forth place conducting about 59% as well as silver.Gold happens to be the best conductor that does not oxidize or tarnish. Therefore, it is used for switch contacts, connector contacts, or other applications exposed to the atmosphere. Copper and Silver must be coated or insulated to protect them from the atmosphere.
