Nickel Silver Sheets - Copper, Zinc, Nickel Alloy | Various Sizes, Polished And Brushed Finish, Corrosion Resistant, Ideal For Decorative And Industrial Applications

An alloy of copper, zinc and nickel, the range of Nickel Silver Sheets are also known as German silver. Procured from reliable vendors, our range has a bright silvery appearance but actually contain no silver. Contain 10-25% nickel and 17-40% zinc with the remainder being copper. Classified by their nickel content with higher nickel contents producing a whiter, silvery color Corrosion resistance increases with higher nickel content and the resulting alloys are less vulnerable to stress corrosion. Strength also increases with nickel content but the increased nickel has little effect on ductility. For industrial applications there is limited advantage in exceeding a nickel content of 18%, however for decorative applications a higher nickel content will provide maximum resistance to stain and tarnish. The spring properties of the alloys are good and remain so at elevated temperatures. The electrical conductivity of nickel silver is much less than that for copper Where a nickel silver alloy is to be machined, lead can be added to the alloy (usually 1-2%) to improve results. However, this will reduce the cold workability of the alloy They are alloys of copper, nickel and zinc and they find many applications in house wares ie cutlery) as well as some industrial applications ie component manufacture).
