Copper

Copper is a malleable and ductile, reddish-orange metal, with high thermal and electrical conductivity. These qualities make the metal ideal for electrical wiring, its most significant commercial use. Copper is one of the few metals that can occur in nature in a directly usable form, and is one of the first metals ever to have been worked by man. It is believed to be have mined for more than 5000 years, and is traditionally considered a coinage metal (along with silver and gold). As a material, Copper is resistant to air and water; it however slowly weathers to an attractive green surface patina, of copper carbonate. For this reason, the material has been seen for centuries as a roofing material for public buildings. Copper is the basis of many highly used alloys, such as brass, bronze and aluminum bronze. Other alloy applications include Sterling Silver, which is used in jewelry, and Cupronickel which is used to make marine hardware and coins.
