Bronze is an alloy of copper with tin, typically around ten percent tin by weight, sometimes with small additions of other elements such as arsenic or phosphorus. Harder and more durable than either component metal alone, and easier to cast than iron at the technology levels available to Bronze Age societies, bronze gave its name to the Bronze Age, the era in which it was the dominant metal for tools, weapons and ornamentation across much of Eurasia and Africa.

Origin YearThe earliest tin bronze artifacts are attested in the Near East, around Susa in present-day Iran, from roughly the late fourth millennium BCE. Primary UseStatuary, bells, ship propellers, bearings and marine fittings, valued for corrosion resistance in seawater and low friction, and, historically, tools and weapons before iron smelting became widespread. 1 Classification

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).
