Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion . Of the large number of different types, the best known traditional types are bronze , where tin is a significant addition, and brass , using zinc instead.
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.
Zinc–copper couple is an alloy of zinc and copper that is employed as a reagent in organic synthesis.The “couple” was popularized after the report by Simmons and Smith, published in 1959, on its application as an activated source of zinc required for formation of an organozinc reagent in the Simmons–Smith cyclopropanation of alkenes.

Devarda's alloy (45% Al, 50% Cu, 5% Zn): chemical reducing agent. Duralumin ; Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons; Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion; Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira
Spelter is a zinc–lead alloy that ages to resemble bronze, but is softer and has a lower melting point. The name can also refer to a copper–zinc alloy (a brass ) used for brazing , or to pure zinc.
A widely used zinc alloy is brass, in which copper is alloyed with anywhere from 3% to 45% zinc, depending upon the type of brass. [125] Brass is generally more ductile and stronger than copper, and has superior corrosion resistance. [125] These properties make it useful in communication equipment, hardware, musical instruments, and water ...
A typical European casting alloy contains 94% tin, 1% copper and 5% antimony. A European pewter sheet would contain 92% tin, 2% copper, and 6% antimony. Asian pewter, produced mostly in Malaysia, Singapore, and Thailand, contains a higher percentage of tin, usually 97.5% tin, 1% copper, and 1.5% antimony. This makes the alloy slightly softer. [5]
