Also known as Copper-Nickel - a metal alloy of copper and nickel - usually 75% copper and 25% nickel. The alloy is used widely throughout the world for coinage because of its long-wearing properties and low cost of production.
(n.) An silver-colored alloy of copper and nickel used to make bullet jackets. U.S. Ball, .30, M1906, and British .303 Small Arms Ammunition Ball MK. VII, for example, were made with cupro-nickel jackets.
A mixture of Copper and nickel used to make many current coins including all the silver coloured current British coins (5p, 10p, 20p, 50p). First used in Great Britain after the use of silver was completely stopped in 1947.
90% copper / 10% nickel alloy which has high corrosion resistance to water containing salt, sulphur, chlorides and other dissolved minerals.
A copper-nickel alloy once used extensively for bullet jackets. It was largely replaced by gilding metal because of barrel fouling problems.
Cupro-Nickel is a mixture of metals, commonly known as an alloy used to make various Australian coins. Cupro-nickel contains 75% copper and 25% nickel. When it is used to make coins, they appear to be made of silver. Although they aren't, because of their appearance, we still call them silver coins.
a mixture of copper, nickel, and possibly other metals. Today this term is most often used to refer to the current coins made by fusing layers of copper and nickel or combination alloy mixtures, resulting in a "sandwich" type of coin. The current US dimes and Quarters are examples. Technically the copper nickel cents, three cent nickels, and regular nickels are cupro-nickel. See "copper nickel".
Composed of an alloy of copper and nickel, as for example U.S. 5 cent coins (other than half dimes) and Canadian 5 cent coins produced since 1982.
composed of an alloy of copper and nickel, such as the U.S. Flying Eagle cents struck from 1856 thru 1858.
a metal alloy, or mixture, of copper and nickel.
Coinage alloy of 75 % copper and 25 % nickel, now widely used as a base metal substitute for silver. A small amount of zinc is added to the alloy in modern Russian coins.
