Bronze is an alloy consisting primarily of copper, ... Silicon bronze has a composition of Si: 2.80–3.80%, Mn: ... and chemical properties.
A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon. Aluminium bronzes are alloys of copper and aluminium. The content of aluminium ranges mostly between 5% and 11%. Iron, nickel, manganese and silicon are sometimes added.
Cannon made of bell metal at Malik-e-Maidan, Bijapur, India. Bell metal or bell bronze is an alloy used for making bells and related instruments, such as cymbals.It is a form of bronze with a higher tin content than most other bronzes, usually in approximately a 4:1 ratio of copper to tin (typically, 78% copper, 22% tin by mass).
Nordic Gold, composed of 89% copper, 5% aluminium, 5% zinc, and 1% tin, is a more recently developed aluminium-bronze alloy for coinage. It was first used for the Swedish 10-kronor coin in 1991, and became widespread after the introduction of Nordic gold 10, 20 and 50-cent Euro coins in 2002.
Islamic Golden Age brass astrolabe Brass lectern with an eagle. Attributed to Aert van Tricht, Limburg (Netherlands), c. 1500.. Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, [1] but copper typically has the larger proportion, generally 66% copper and 34% zinc.
Phosphor bronze propeller salvaged from 1940s American warship.. Phosphor bronze is a member of the family of copper alloys.It is composed of copper that is alloyed with 0.5–11% of tin and 0.01–0.35% phosphorus, and may contain other elements to confer specific properties (e.g. lead at 0.5–3.0% to form free-machining phosphor bronze).
White bronze is a white-coloured alloy. Examples of various alloys composed of copper, tin and zinc or composed of zinc, copper, aluminum and magnesium. [1] [2] A modern composition contains 55% copper, 30% tin and 15% zinc. [3] A 1904 patent for "white bronze" is composed of 86% zinc, 9.9% copper, 4% aluminum and 0.1% magnesium. [1]
Gunmetal ingot is a related alloy in which the zinc is replaced by 2% lead; this makes the alloy easier to cast but it has less strength. [2]Modified gunmetal contains lead in addition to the zinc; it is typically composed of 86% copper, 9.5% tin, 2.5% lead, and 2% zinc.
