GERMAN SILVER; German silver, also known as Nickel silver, Argentann, paktong, new silver, nickel brass, or alpacca (or alpaca), is a copper alloy with nickel and often zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc. In fact, 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.
Nickel silver is named for its silvery appearance, but contains no elemental silver unless plated
