Oerlikon Nifil NiCu7 description: NIFIL NiCu7 is used for welding of similar alloys such as 70Ni-30Cu (Monel). Suitable for joining and surfacing also on unalloyed / low alloy steels and cast steels. The weld metal has a high corrosion resistance in saline solution and sea water. Typical applications are in the chemical industry, food processing plant and seawater desalination plants. NIFIL NiCu7 contains sufficient titanium to control weld metal porosity and for grain refinement. Solid wire for welding or hard-facing alloys with the same chemical composition. Good appearance and excellent resistance to corrosion in saline environments.
