Nickel-silver (German silver)

Nickel-silver is a silver colored copper-nickel-zinc alloy with high corrosion resistance and high strength. Nickel-silver can only be hardened with cold working, e.g. by forging or rolling. Temperatures over 500°C are required to soften it again.

Further names for nickel-silver include:

  • Argentan
  • German silver ("plata alemana" in Spanish)
  • Alpacca
  • Paktong

Nickel-silver application areas:

  • Silverware and tableware
  • Devices for precision engineering, electrical technology, medical applications
  • Shielding EMI
  • Zippers
  • Jewelry
  • Wind and string instruments
  • Frames for Glasses 

Nickel-silver foils are used in the following areas:

  • Electrical technology
  • Lamination
  • Etching technology
  • Antennas and contacts in telecommunications

We offer the following standard types of nickel-silver:

  • CuNi18Zn20 (DIN: CuNi18Zn20; UNS: C 76400; EN: CuNi18Zn20)

Other types of nickel-silver can be requested; we would be happy to assist you.
