Automig Nicu-7 / Tigfil Nicu-7: Ernicu-7 Sni 4060

This document provides information on solid welding wire used for nickel-copper alloy welding. The wire has a typical 65Ni/30Cu/3Mn/2Ti composition and is classified as SNi 4060 and ERNiCu-7. It can be used for welding Monel and NiCu alloys to themselves or to mild steel. Typical applications include heat exchangers, piping, vessels and components in salt purification and food/pump/valve manufacturing. The wire is supplied on spools in 1.2mm, 1.6mm or 2.0mm diameters with mechanical properties varying based on shielding gas used.
