  • copper processing . Definition, History, & Facts . Britannica

    In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face centred cubic crystal structure, and there is no critical temperature at which this crystal structure changes. Consequently, it is ductile and possesses a high level of electrical and thermal conductivity, making it.
