![]() ![]() Composition ranged from high-copper to brasses.īeryllium copper Heat treatable copper-beryllium alloy of high strength and hardness. ![]() ![]() Brassware is decorated with Sanskrit inscriptions and Hindu icons.īenin Bronze Cast copper alloy products of great artistry and craftsmanship produced in Benin, Nigeria from the 13th to 19th centuries. It is in Utah Pradesh which has a long history of copper mining. ![]() The term was also sometimes confusingly used in the nineteenth century to describe a 60/40 cast brass.īenares Ware Benares, now called Varenisi, is the Hindu Holy City and is sited in the River Ganges in India. It is too brittle to be used for many other applications. It is used primarily for the manufacture of boiler fireboxes.Īrsenical brass Brass with improved corrosion resistance containing arsenic, and frequently aluminium.īell metal Copper tin alloy with much higher tin content than conventional bronze in order to make it hard and sonorous. After annealing, quenching is not necessary but may be of advantage in helping to remove scale.Īnode copper Cast slabs of copper from the fire refining processes used as starters for electrolytic refining.Īrgentan Early name for nickel silver, also alfenide.Īrgyrolith Another early name for nickel silver, also alfenide.Īrsenical copper Copper with phosphorus and arsenic additions that give good strength and resistance to fire cracking. Also called Key of Life and Crux Ansata.Īnnealing Heating a metal in order to soften it after hardening by cold work or heat treatment. They are therefore commonly used for making propellers, bearings, gears, valves, and pipefittings for seawater use.Īnkh Ancient Egyptian symbol for life adopted by Greek philosophers as the sign for copper. These alloys are strong, hard and have excellent resistance to marine corrosion. This is often used for condenser tubes.Īluminium bronze Copper-aluminium alloys with up to 13% of aluminium, usually also with other additions such as iron, manganese, nickel and/or silicon. They are used for castings, extrusions and for hot stampings.Īluminium brass High copper brass with aluminium added for improved corrosion resistance. Also a metallurgical term to describe hardening an alloy by heating to a temperature where a precipitate forms from a super-saturated solid solution.Īle warmer Copper or brass vessel, tinned internally, shaped with a conical or bulbous foot suitable for use in a fire or grate to warm ale.Īlphenide Nickel silver, generic term, also argentanĪlpakka Nickel silver, 65% copper, 22% zinc, 13% nickelĪlpha brass Brass containing up to 36% of zinc is usually the single alpha phase with good cold working properties.Īlpha-beta brass Brass containing over 36% of zinc or with other additions usually has two phases present in the crystal structure, alpha and beta. This will cover composition, form, condition and properties.)Ībbreviations for element names Aluminium - Al, Copper - Cu, Iron - Fe, Gold - Au, Lead - Pb, Manganese - Mn, Nickel - Ni, Silver - Ag, Tin - Sn.Īdmiralty brass 70/30 brass with 1% tin added for extra corrosion resistance.Īdnic 70% Copper, 29% nickel, 1% tin alloy for resistance to corrosion and heat.Īgeing Loose term covering some surface treatment techniques used to make objects look old. (If ordering copper alloys in serious quantities for production, always ensure that a current standard is specified, not just a name. Some other sources do not agree on a few of these terms! Sources are mainly various metallurgical dictionaries, catalogues and other references. Trade names and most industrial terms are generally not included except where thought to be in common use.īrass is conventionally described as ‘% copper/ % zinc’ but also has many other industrial designations and specifications mentioned. Some of them have been used very loosely in the past and many of the older names for alloys have many variations in composition quoted in different sources. Most terms are current but others are obsolescent or obsolete terms that occur in some of the useful literature. This includes many terms relevant throughout the website covering antique and collectible copper and brass. Small extracts can be used with acknowledgements to '' website. ![]()
