Copper Nickel alloys

Special CuNiAl, special CuNiMnFe & other CuNi products

CuNi bars

Excellent corrosion resistance. _High mechanical properties. _Machinability. _Weldability.

Discover our wide range of Copper-Nickel alloys. They all offer great corrosion resistance and can be used in salty water media.

  • Special CuNiAl products bring outsanding mechanical properties on top of it: for example K5 and K7 alloys.
  • Our CuNiMnFe products include the famous Navinic product range of "90/10" and "70/30" alloys.
  • Other CuNi alloys can be a material of choice for electrical resistivity applications.
