Copper (Cu) is an element from the group of transition metals of the Periodic Classification of Elements, having a density of 8.96 g/cc and a melting point of 1083°C. After melting and purification it is a soft metal with very good thermal and electrical conductivity. Copper is very chemically resistant and therefore included in semi-precious metals. It is not acid-affected by non-oxidizing conditions. Under the influence of atmospheric conditions, copper undergoes surface corrosion, gradually being covered by a characteristic green patina. Copper can be processed in cold and hot forming processes.
