NICKEL COPPER ALLOYS

Nickel Copper Alloys (NiCu) and their welding consumables have a Ni content of 50-70 % and are known as Silverin alloys.

Application example:

  • (NiCu45) Silverin 404  is used for electronic components due to its low magnetic permeability.
  • (NiCu30Fe) Silverin 400 has excellent resistance to liquid acids and seawater corrosion. Typical applications are plant and apparatus construction, as well as Ship Building.
  • (NiCu30Al) Silverin 500  can be age-hardened due to the increased Aluminum and Titanium content.  The final hardness of the material prior to precipitation treatment is between 24-44 HRC. A prime application is the manufacturer of doctor blades used in the paper industry. This alloy is also used to produce springs for the Ship Building Industry.
  • IGS-Silverin 418 is the welding grade used to produce Strip Electrodes. This is used for overlay cladding of parts in the petrochemical and marine industries.
