CEWELD


CuNi30Fe GMAW-GTAW Solid wires




CuNi30Fe

 
TYPE 
Copper-Nickel alloyed Mig / Tig welding wire.
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.
PROPERTIES 

Sound, pore free deposits on ferrous and non-ferrous base materials offering excellent resistance to corrosion in sea water.
