ALLOY 67  Wire for SAW Fili per Arco Sommerso.

ALLOY 67 Wire for SAW Fili per Arco Sommerso.

Filler Metal ALLOY 67 is used for submerged-arc welding 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. Submerged-arc welding with Filler Metal Alloy 67 is done with suitable submerged arc flux. 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:
Tensile Strength: MPa 345 (psi 50,000)
Elongation, (4d) % 30

Filler metals wires are available on spools or in coils and in a variety of diameters.
