All About Copper

Copper is generally considered corrosion-resistant. It naturally has a reddish-brown color, which is due to the formation of a copper oxide passivation film on the metal's surface. Over time, a green copper carbonate will form on the surface (think, Statue of Liberty) as the copper oxide reacts with water and carbon dioxide in the air.
