Nickel-Silver alloys

CuNiZn products: ARCAP® and other Nickel-Silver products

Mechanical strength. _Corrosion resistance. _A-magnestism. _Machinability. _"Silver" color.

Discover our range of nickelsilver alloys including ARCAP® (AP1D, AP1C, AP4, etc): special high end alloys with exceptionnal machining, cryogenic and magnetic properties. We also produce special Manganese two-phase nickelsilver, for reinforced strength and machinability, such as NM2 and NM436, and a lead-free machinable EnviN alloys.

  • High durability of components
  • Precision and quality of machining

Nickel-silver also called "German silver" or "nickel brass" are alloys combining Copper with Nickel and Zinc. They offer a unique combination of properties, such as mechanical strength and corrosion resistance superior to those of brass, excellent machinability, good electrical resistivity and their silver color while not containing Silver.
