Filler metal used for MIG, TIG, oxyacetylene and submerged arc welding of wrought or cast copper-nickel

CuNi30 is known for its strength, workability, formability, and weldability. The addition of nickel strengthens the weld metal and improves the corrosion resistance, particularly against salt water. The inclusion of controlled quantities of iron also gives the alloy an extraordinary resistance to general corrosion and stress corrosion cracking, as well as to erosion. It also protects against impingement due to turbulent water containing air bubbles and silt flowing at high velocities. The weld metal has good hot/cold ductility. Welding is done in all positions. When welding with the GTAW and GMAW processes, no preheat is required.
