a metal with a red-orange color. It has the chemical symbol 'Cu' and is positioned in the Periodic Table near silver and gold. It has extraordinary physical properties. So it exhibits behind silver the highest electrical and thermal conductivity . Because of its corrosion resistance it can be used also for long term applications. Its main use is in the electrical and electronic industry. By recycling it can be used repeatedly. By forming alloys the properties can be changed in a broad spectrum. It is produced in a high purity by electrorefining and electrowinning
