Nickel silver

Nickel silver : copper, zinc and nickel alloy


Nickel silver is an alloy of copper, zinc and nickel which must consist of at least 5% nickel, at least 20% zinc and at least 45% copper.
Nickel silver has several qualities that other alloys do not possess and which make it so successful in use:
