Bronze is a powerful alloy made up primarily of copper, typically mixed with about 12–12.5% tin, and frequently paired with the addition of other metals like aluminum, manganese, nickel or zinc, along with sometimes non-metals or metalloids such as arsenic, phosphorus or silicon. These additives create a variety of alloys that may be tougher than copper alone, or have other useful properties, including stiffness, flexibility, or machinability. The historical period when bronze was the hardest metal in widespread use is known as the Bronze Age. The beginning of the Bronze Age in India and western Eurasia is typically dated to the mid-4th millennium BC, and to the early 2nd millennium BC in China; it gradually spread across regions. The Bronze Age came to a close with the Iron Age starting from about 1300 BC and spreading to most of Eurasia by about 500 BC, even though bronze continued to be used far more widely than today. Because ancient items were often made from bronzes (copper and zinc) and bronzes with different compositions, modern museums and scholarly descriptions of older objects increasingly use the broader term copper alloy instead. The discovery of bronze enabled people to make metal items that were stronger and more long-lasting than ever before. Bronze tools, arms, armor, and construction materials like decorative tiles were harder and more durable than their stone and copper predecessors. Initially, bronze was created out of copper and arsenic, producing arsenic bronze, or from naturally or artificially mixed ores of copper and arsenic. The earliest known artifacts come from the Iranian plateau in the 5th millennium BC. It was only later that tin became part of the alloy, becoming the main non-copper ingredient of bronze by the late 3rd millennium BC. Tin bronze was superior to arsenic bronze because it could be produced more easily and was stronger as well as easier to cast. Moreover, unlike arsenic, metallic tin is not poisonous. The earliest known tin-alloyed bronze dates back to 4500 BC in a Vinča culture site in Pločnik (Serbia). Early examples date to the late 4th millennium BC in Egypt, Susa (Iran), and ancient sites in China, Luristan (Iran), and Mesopotamia (Iraq). Ores of copper are typically not mixed with ores of the far less common tin, but this was true of most parts of the world during history, apart from some instances like Cornwall in Britain or certain other ancient areas. As a result, bronze manufacture in serious cases often needed trade for years to obtain high quality ore. Tin resources and commerce throughout historical times influenced social and economic advancements significantly. In Europe, tin deposits found their major resource base on the deposits of tin-bearing ores in Britain's Cornish mining areas which had spread across vast expanses to regions of eastern Phoenicia within the Mediterranean. It shows the widespread trade connections during ancient periods. All around the world, hoards containing bronze are widely seen; that metal has been seen by society for ages as a form of value and sign of elite social position or wealth status also holds. Bronze objects discovered in many sites suggest it not only signifies a great level of expertise to forge something so powerful yet rare at those times. This is quite evident when seeing large deposits in China - known throughout its ancient time - for both royal burial gifts as well as day-to-day ritual practices using it. Large collections have even been documented showing its use in tools made during periods around ancient dynasties; though no concrete date marks are clear evidence here because their craftsmanship demonstrates so little variation through history with bronze still seen highly effective today for producing items lasting long durations when not used carelessly due poor preservation methods that can cause weakening from air exposure. Today, the main reasons why manufacturers have kept on choosing aluminum and other strong components like copper for crafting parts like motor bearings lie deeply rooted. As previously established; many well known modern industries using them will benefit even further by applying its superior characteristics while working. One great point about such use - bronze maintains high level precision once molded which provides long life to components used extensively every day. When combined together this really sets bronze up apart from its direct counterpart – steel!
