Market Synopsis Bronze is an alloy of copper and tin. The proportions of copper in bronze vary widely from 67% to 95%. Some modern bronzes contain no tin at all, substituting other metals such as aluminum, manganese, phosphorus, silicon, arsenic, and zinc. Bronze is reddish brown in color and its history dated back to 3500 BC. Bronze alloy is hard, ductile, and more fusible metal (i.e., more readily melted), which makes it easier to cast. Many bronze alloys expand a little during solidifying from liquid to a solid state, which is desirable during sculpture casting as it helps to fill a mold. It exhibits brittleness, however, less than cast iron. Striking bronze against a hard surface doesn't generate sparks, unlike steel, which makes bronze useful around flammable or explosive materials. Upon exposure to air, bronze oxidizes and forms an oxide layer on the surface called patina, which consists of copper oxide and it eventually becomes copper carbonate. The oxide layer protects the interior metal from further corrosion. However, if chlorides are present (as from seawater), copper chloride is formed, which can cause "bronze disease" -- a condition in which corrosion works through the metal and destroys it. Additionally, exposure of chlorides and sulfur makes the patina of pale green and brown color respectively on the bronze. Through its discovery, bronze has been used for making various artifacts & sculpture, armor & weapons, tools, coins & medals, bronze mirrors, traditional building material such as bronze
