Nickel Silver
Nickel silver is made up generally of Copper, Zinc and Nickel. The nickel content gives the alloy a silvery appearance, making it ideal for use in the decorative industry, i.e. jewellery, cutlery, and coin manufacturing. It is also widely used in photochemical etching for electrical applications. Allied Copper Alloys are a leading U.K. distributor of Nickel Silver supplied in coil and cut blanks.
Thicknesses ranging from:
0.05mm – 4.0mm
Whatever your requirement,
10kgs – 10,000kgs we can help.
In-house precision slitting from
5mm – 670mm

| CuNi10Zn27 | CW401J | C74500 | NS103 | CuNi10Zn27 is a Copper Alloy with good corrosion resistance in rural and marine atmospheres. It has excellent cold working properties and is suitable for various forming processes. It offers many benefits including good formability, readily soldered or brazed and attractive colour. However, it has poor hot working characteristics. | Decorative, Industrial, Marine |
| CuNi12Zn24 | CW403J | C75700 | NS104 | Similarly to CuNi10Zn27, CuNi12Zn24 has good resistance to atmospheric corrosion, offering resistance to both neutral and alkaline solutions, however resistance to oxidising acids is poor. The alloy has good cold forming properties but poor machinability. | Industrial, Telecommunications, Decorative, Marine |
| CuNi18Zn20 | CW409J | C76400 | NS106 | CuNi18Zn20 has good resistance to atmospheric corrosion with good cold formability and spring properties. It is suitable for many decorative applications and becomes progressively whiter with increased nickel content. It has a much lower sensitivity to SCC than Brasses. | Electronics, Telecommunications, Decorative |
| CuNi18Zn27 | CW410J | C77000 | NS107 | CuNi18Zn27 provides good corrosion resistance, good formability, and good tarnish resistance. Its colour makes it ideal for decorative purposes. | Electronics, Telecommunications, Decorative |
| CuNi9Sn2 (Alloy 725) | CW351H | C72500 | - | With a good combination of fatigue strength, formability and resistance to corrosion, CuNi9Sn2 (Alloy 725) offering manufacturers many benefits, particularly for electrical components. | Telecommunications, Electronics |
