bronze
Sign in to saveBronze 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 some of which are harder than copper alone or have other useful properties, such as strength, ductility, or machinability.
AI overview
Bronze is a metal mixture made primarily of copper combined with tin and sometimes other metals or elements like aluminum, manganese, or zinc. It matters because these additions make bronze harder and stronger than copper alone, giving it useful properties like improved strength, flexibility, and ease of shaping.

The archaeological period during which bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in western Eurasia is conventionally dated to the mid-4th millennium BCE (~3500 BCE), and to the early 2nd millennium BCE in China; elsewhere it gradually spread across regions. The Bronze Age was followed by the Iron Age, which started about 1300 BCE and reached most of Eurasia by about 500 BCE, although bronze continued to be much more widely used than it is in modern times.
