ALLOY 67 Mig Welding Rods Filler Metal
Filler Metal ALLOY 67 is used for gas-metal-arc-welding (Mig) of MONEL® alloy 450 (70/30 Copper-Nickel) and other copper-nickel alloys.It is used for surfacing of steel if a barrier layer of Nickel Filler Metal 61 is first applied. If applied by the submerged-arc process, Filler Metal Alloy 60 can be used for the barrier layer.
The copper-nickel weld metal has excellent resistance to corrosion in sea water, and is widely used for marine and desalination applications.
Dissimilar-welding applications for Filler Metal 67 are joints between MONEL® alloys or Nickel 200® and copper-nickel alloys.
Minimum Mechanical Properties:
