What is AWS Class ERNiCu-7 MIG and TIG Filler Metal?

AWS Class ERNiCu-7 MIG and TIG filler metal rods and wires are designed nickel-copper alloys to have the best corrosion resistance in seawater and chemical solutions. They are usually composed of Nickel 6269% Copper 2933% Manganese 13% Titanium 0.51.5% Iron and Silicon to strengthen and weld. Mechanical characteristics are tensile strength in the range of 480 Mpa, yield strength in the range of 170 Mpa, and elongation of the range of 40-45 percent as a result of which it boasts of fabulous ductile and toughness. ERNiCu-7 it is used in welding nickel-copper alloys and when it is necessary to retain the strength and resisting to corrosion in marine and chemical process.

AWS Class ERNiCu-7 MIG and TIG Filler Metal Filler Metal Uses

AWS Class ERNiCu-7 MIG and TIG filler rods and wires are generally used when welding nickel-copper alloys especially Monel 400 and 404, but also in joining nickel-copper to other alloys. They are very resistant to seawater, salt and acidic environments; hence, they are useful in marine engineering, ocean desalination plants, shipbuilding and offshore constructions. They have also found wide application in chemical processing equipment, heat exchangers, pumps and piping systems that are subject to corrosion. ERNiCu-7 has the best toughness, weldability, and corrosion resistance, which makes it a good choice as the desired one when there is need to have strong and durable welders, thus it is used worldwide in the most critical industrial and marine jobs.
