IANICU700001250TL0 - Monel 60 TIG Rod 1/8" (3.2mm) ERNiCu-7 Filler Metal

ERNiCu-7 Nickel-Copper TIG Welding Rod - 1/8" x 36"

The ERNiCu-7 TIG Welding Rod is a premium Nickel-Copper filler metal designed for Gas Tungsten Arc Welding (GTAW) of Monel alloys. With a diameter of 1/8" (3.2mm) and a standard length of 36 inches, this rod meets AWS A5.14 specifications, ensuring consistent chemistry and performance. The alloy composition is approximately 65% Nickel and 30% Copper, with additions of Manganese and Titanium to control porosity and enhance strength.

Key Performance Characteristics:
This filler metal is renowned for its outstanding corrosion resistance. It performs exceptionally well in marine environments, resisting pitting and stress corrosion cracking in sea water. It is also highly resistant to reducing acids and salts, making it a standard choice for fabricating heat exchangers, evaporators, and piping systems in the chemical and petrochemical industries. The weld deposit matches the mechanical properties and color of base metals like Monel 400.

Versatile Applications:
Fabricators rely on ERNiCu-7 for more than just joining Monel to Monel. It is frequently used for welding Monel alloys to steel, joining copper-nickel alloys to steel, and for surfacing steel parts to protect against erosion and corrosion. When used for overlaying, the first layer is often applied with this rod to establish a sound metallurgical bond before subsequent layers. For optimal results, clean base metals thoroughly to remove oxides and impurities, and use 100% Argon shielding gas to prevent contamination.

Whether you are repairing marine hardware or fabricating pressure vessels, the ERNiCu-7 TIG rod delivers the ductility and strength required for high-integrity welds. Its controlled composition minimizes the risk of hot cracking, a common challenge in nickel-alloy welding.
