Wrought Materials - Copper-Nickel-Zinc Alloys - Nickel Silvers

Common names: 12% Nickel Silver

Nickel Silver 65-12

A copper-nickel-zinc alloy with an alpha phase structure. The alloy has good corrosion resistance to rural, industrial and marine atmospheres and to fresh water. Since it has good cold formability and an attractive soft ivory-white colour, the material is often used for decorative applications. The most commonly used wrought forms are sheet, strip, rod, tube and wire.
