It has been used going all the way back to the 8000BC, where it was one of the first metals to be used by humans. It has been known to corrode with a patina of green along its surface. Copper has a number of different uses and purposes. It has a high electrical and heat conductivity, which makes it perfect to be used in electrical wirings, where it can be lined with other wires. It can also be used in motors for the same reasons.  Copper alloys are used in all US coins, and most gun metals contain traces of copper.  Most famously, the Statue of Liberty is actually made out of copper, but has the green patina along its surface, due to decades of corrosion. Copper can also be smelted together to form other alloys. When combined with zinc, it will create brass, which is used for decoration or ornamentation, coverings over doorknobs, etc. When fused together with tin, it creates bronze, which was first discovered around 4000BC, and can be used for weapons (Bronze Age) , tools, construction, and statues.
