What is "nickel silver"

Nickel \Nick"el\, n. [G., fr. Sw. nickel, abbrev. from Sw. kopparnickel copper-nickel, a name given in derision, as it was thought to be a base ore of copper. The origin of the second part of the word is uncertain. Cf. Kupfer-nickel, Copper-nickel.]

1. (Chem.) A bright silver-white metallic element of atomic number 28. It is of the iron group, and is hard, malleable, and ductile. It occurs combined with sulphur in millerite, with arsenic in the mineral niccolite, and with arsenic and sulphur in nickel glance. Symbol Ni. Atomic weight 58.70.

   Note: On account of its permanence in air and inertness to oxidation, it is used in the smaller coins, for plating iron, brass, etc., for chemical apparatus, and in certain alloys, as german silver. It is magnetic, and is very frequently accompanied by cobalt, both being found in meteoric iron.

2. A small coin made of or containing nickel; esp., a five-cent piece. [Colloq. U.S.]

   Nickel silver, an alloy of nickel, copper, and zinc; -- usually called german silver; called also argentan.

n. A hard, corrosion-resistant alloy of copper, zinc and nickel used to make domestic silverware.

n. a silver-white alloy containing copper and zinc and nickel [syn: German silver]

Nickel silver, Mailechort, German silver, Argentan, new silver, nickel brass, albata, alpacca, or electrum is a copper alloy with nickel and often zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc. Nickel silver is named for its silvery appearance, but it contains no elemental silver unless plated. The name "German silver" refers to its development by 19th-century German metalworkers in imitation of the Chinese alloy known as paktong ( cupronickel). All modern, commercially important nickel silvers (such as those standardized under ASTM B122) contain significant amounts of zinc, and are sometimes considered a subset of brass.
