Classification and Properties of Copper Alloys :: Total ...

Copper has been mined for more than 10,000 years with a copper pendant found in current day Iraq being dated to 8700BC. By 5000BC copper was being smelted from simple copper oxides. The first high-strength copper alloy gave its name to an era, the Bronze Age, which followed the Copper (Chalcolithic) Age more than 4,000 years ago.
