Copper (Cu) is a red-orange metallic transition metal from the 11th group of the periodic table. The word origin of copper lies in the Latin word “Cyprium”, meaning as much as “ore from the greek island Cyprus”, in reference to the local copper production in ancient times. Copper is one of the few metals occurring as a native metal and has been used by humankind from as early as 5000 BC onwards. In the earth’s crust, copper is present at a content of about 50 ppm.
Copper is soft, ductile and possesses a high thermal and electrical conductivity. This makes it predestined for the application as heat sinks and in the form of wire, for power generation and transmission, telecommunications and general electrical equipment. In integrated circuits, copper increasingly replaces aluminium, because of its superior electrical conductivity. Above that, copper is resistant to erosion caused by moisture, making it attractive for the usage in pipes and jewellery. For some applications, pure copper is too soft, which is overcome by alloying it with e.g. tin (bronze) or zincccc (brass).
Furthermore, copper contributes to the field of photovoltaics, where in the form of CIGS sputter targets it contributes to the fabrication of photovoltaic cells.
