Alpha brass (containing less than 35 per cent of zinc) is used for most engineering materials requiring forging, pressing, etc. Alpha-beta brass (35–45 per cent zinc) is used for hot working and extrusion. Beta brass (45–50 per cent zinc) is used for castings. Small amounts of other metals, such as lead or tin, may be added brazing solderan alloy of copper and zinc for joining two metal surfaces by melting the alloy so that it forms a thin layer between the surfaces Britannia metalan alloy of low melting point consisting of tin with 5–10 per cent antimony, 1–3 per cent copper, and sometimes small quantities of zinc, lead, or bismuth: used for decorative purposes and for bearings bronzeany hard water-resistant alloy consisting of copper and smaller proportions of tin and sometimes zinc and lead chromela nickel-based alloy containing about 10 per cent chromium, used in heating elements constantanan alloy of copper (60 per cent) and nickel (40 per cent). It has a high resistivity that does not vary significantly with temperature and is used in resistors and, with copper, in thermocouples cupronickelany ductile corrosion-resistant copper alloy containing up to 40 per cent nickel: used in coins, condenser tubes, turbine blades, etc Duralumin(trademark)a light strong aluminium alloy containing 3.5–4.5 per cent of copper with small quantities of silicon, magnesium, and manganese; used in aircraft manufacture electruman alloy of gold (55–88 per cent) and silver used for jewellery and ornaments ferrochromiuman alloy of iron and chromium (60–72 per cent), used in the production of very hard steel ferromanganesean alloy of iron and manganese, used in making additions of manganese to cast iron and steel ferromolybdenuman alloy of iron and molybdenum used in making alloy steels ferronickelan alloy of iron and nickel used in making nickel steels ferrosiliconan alloy of iron and silicon, used in making cast iron and steel Invar(trademark)an alloy containing iron (63.8 per cent), nickel (36 per cent), and carbon (0.2 per cent). It has a very low coefficient of expansion and is used for the balance springs of watches, etc kamacitean alloy of iron and nickel, occurring in meteorites magnolia metalan alloy used for bearings, consisting largely of lead (up to 80 per cent) and antimony, with the addition of smaller quantities of iron and tin magnoxan alloy consisting mostly of magnesium with small amounts of aluminium and other metals, used in fuel elements of nuclear reactors Manganin(trademark)an alloy of copper containing manganese (13–18 per cent) and nickel (1–4 per cent): it has a high electrical resistance that does not vary greatly with temperature and is used in resistors misch metalan alloy of cerium and other rare earth metals, used esp as a flint in cigarette lighters Monel or Monell metalany of various silvery corrosion-resistant alloys containing copper (28 per cent), nickel (67 per cent), and smaller quantities of such metals as iron, manganese, and aluminiumNichrome(trademark)any of various alloys containing nickel, iron, and chromium, with smaller amounts of other components. It is used in electrical heating elements, furnaces, etc nickel silverany of various white alloys containing copper (46–63 per cent), zinc (18–36 per cent), and nickel (6–30 per cent): used in making tableware, etc nimonic alloyany of various nickel-based alloys used at high temperatures, as in gas turbine blades ormolua gold-coloured alloy of copper, tin, or zinc used to decorate furniture, mouldings, etc oroidean alloy containing copper, tin, and other metals, used as imitation gold osmiridiuma very hard corrosion-resistant white or grey natural alloy of osmium and iridium in variable proportions, often containing smaller amounts of platinum, ruthenium, and rhodium: used esp in pen nibs permalloyany of various alloys containing iron and nickel (45–80 per cent) and sometimes smaller amounts of chromium and molybdenum pewterany of various alloys containing tin (80–90 per cent), lead (10–20 per cent), and sometimes small amounts of other metals, such as copper and antimony phosphor bronzeany of various hard corrosion-resistant alloys containing copper, tin (2–8 per cent), and phosphorus (0.1–0.4 per cent): used in gears, bearings, cylinder casings, etc pinchbeckan alloy of copper and zinc, used as imitation gold platinaan alloy of platinum and several other metals, including palladium, osmium, and iridium platiniridiumany alloy of platinum and iridium: used in jewellery, electrical contacts, and hypodermic needles soft solderan alloy of lead and tin for joining two metal surfaces by melting the alloy so that it forms a thin layer between the surfaces speculum metala white hard brittle corrosion-resistant alloy of copper (55–70 per cent) and tin with smaller amounts of other metals. It takes a high polish and is used for mirrors, lamp reflectors, ornamental ware, etc steelany of various alloys based on iron containing carbon (usually 0.1–1.7 per cent) and often small quantities of other elements such as phosphorus, sulphur, manganese, chromium, and nickel. Steels exhibit a variety of properties, such as strength, machinability, malleability, etc, depending on their composition and the way they have been treated Stellite(trademark)any of various alloys containing cobalt, chromium, carbon, tungsten, and molybdenum: characteristically very hard and wear-resistant, they are used as castings or hard surface-coatings sterling silveran alloy containing not less than 92.5 per cent of silver, the remainder usually being copper ternean alloy of lead containing tin (10–20 per cent) and antimony (1.5–2 per cent) tombac or tambacany of various brittle alloys containing copper and zinc and sometimes tin and arsenic: used for making cheap jewellery, etc type metalan alloy of tin, lead, and antimony, from which type is cast white goldany of various white lustrous hard-wearing alloys containing gold together with platinum and palladium and sometimes smaller amounts of silver, nickel, or copper: used in jewellery zircalloyan alloy of zirconium containing small amounts of tin, chromium, and nickel.
