High Quality Content by WIKIPEDIA articles! Nickel silver is a metal alloy of copper with nickel and often, but not always, zinc. The usual formulation is 60% / 20% / 20% copper / nickel / zinc. It is named for its silvery appearance, but contains no elemental silver unless plated. Other common names for this alloy are German silver, paktong, new silver and alpacca (or alpaca). Nickel silver first became popular as a base metal for silver plated cutlery and other silverware, notably the electroplated wares called EPNS (electro-plated nickel silver). It is used in zippers, better-quality keys, costume jewellery, for making musical instruments (e.g., cymbals, saxphones), and is preferred for the track in electrically powered model railway layouts as its oxide is conductive. It is widely used in the production of coins (e.g. GDR marks, Portuguese escudo). Its industrial and technical uses include marine fittings and plumbing fixtures for its corrosion resistance, and heating coils for its high electrical resistance.
