Copper as one of the most important metals belongs to the transition and/or half precious metals. It is a relatively hard, at the same time very tough and flexible metal, which can be formed extraordinarily well into very thin lamellas and fine wires. Pure copper is red and thus beside gold the only coloured metal. With regards to its heat- and electrical conductivity it is situated between silver and gold. Copper can be alloyed very well, whereby it can be hardened considerably. The metal has a good chemical stability. Exposed to air it becomes only slowly covered with greenish patina (a mixture of basic sulphates, carbonates as well as chloride), which protects it against further...
