The copper alloy range containing 10-20% nickel, in addition to zinc, is known as nickel silver and can be regarded as a special brass. The metal has an attractive silvery appearance rather than the typical brassy colour.
In most respects nicker silvers show similar corrosion resistance characteristics to brasses, but the higher nickel versions have superior tarnish resistance and resistance to stress corrosion cracking.
They are available in all forms and are used for decorative applications, jewellery, model making, toothbrush anchor wire and pins, musical instruments e.g. 'silver bands', flutes etc, ball point refills, ferrules for woodwinds, bagpipes and fishing rods, test probes and Bourdon springs.
