Prior to the introduction of cupronickel, which was widely adopted by countries in the latter half of the 20th century, [59] alloys of copper and silver were also used, with the United States using an alloy of 90% silver and 10% copper until 1965, when circulating silver was removed from all coins with the exception of the half dollar—these ...
Leaded copper is a metal alloy of copper with lead. A small amount of lead makes the copper easier to machine. Alloys with a larger amount of lead are used for bearings. Brass and bronze alloys of copper may have lead added and are then also sometimes referred to as leaded copper alloys. [1] Leaded copper and its alloys have been used since ...
Irogane (色金 "coloured metals") [1] [2] [3] is the term for a set of Japanese metals – forms of copper (with natural impurities), and copper alloys – treated in niiro patination processes, [4] [5] traditionally used in sword-making, catches for sliding doors, and luxury highlights on larger objects, and in modern times, in jewellery.
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).
