Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color.It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys.n the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as aes Ñyprium (metal of Cyprus), later corrupted to Ñuprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived.
