Bronze is a copper-tin alloy with at least 60% copper share. The commercial production of bronze began between 2500 and 2000 BC in the Middle East. Bronze is therefore one of the first alloys created and used by man and plays an important role in the history of people. Today bronze is used in mechanical and tool engineering, in electrical engineering and drive technology as well as in medical technology. Also the chemical and food industries use the anti-corrosive and wear resistance properties offered by bronze.
