Nickel Silvers

White alloys consisting of copper, zinc and nickel. The copper content usually lies between 55 and 63 percent while the nickel ranges from 10 to 30 percent. As the nickel content is in­creased, the corrosion and tarnish-resisting properties in certain media are improved. Nickel silver wire is used in jewelry and for other decorative purposes, for cold heading, thread rolling and springs. The alloys serve as an excellent basis for silver plating.
