CuNi30Fe Tig GMAW-GTAW Solid wires




CuNi30Fe Tig

 
TYPE 
Copper-Nickel alloyed Tig filler metal.
APPLICATIONS 
This Copper-Nickel weld metal is widely used for marine and desalination applications. Dissimilar welding applications for this alloy are joints between Monel alloys or Nickel 200 and Copper-Nickel alloys. Often used for surfacing on steel by using Ceweld NiTi-3 as a barrier layer. Shipbuilding, seawater evaporation plants, tubes, pump building, offshore, desalting equipment and parts etc.
