Bronze is an alloy consisting primarily of copper, commonly with about 12–

12.5% tin and often with the addition of other metals


(including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such
as phosphorus, or metalloids, such as arsenic or silicon. These additions produce a
range of alloys that may be harder than copper alone, or have other useful
properties, such as strength, ductility, or machinability. The archaeological period in
which bronze was the hardest metal in widespread use is known as the Bronze Age.
The beginning of the Bronze Age in western Eurasia and India is conventionally
dated to the mid-4th millennium BC (~3500 BC), and to the early 2nd millennium
BC in China;[1] elsewhere it gradually spread across regions. The Bronze Age was
followed by the Iron Age starting about 1300 BC and reaching most of Eurasia by
about 500 BC, although bronze continued to be much more widely used than it is in
modern times.
