AWS Class ERNiCu-7 is primarily made up of nickel (about 65–70%) and copper (20–30%), along with small amounts of iron, manganese, and titanium to enhance weldability and minimize porosity. This alloy is known for its outstanding corrosion resistance, particularly in saltwater and acidic conditions. The weld metal typically shows tensile strengths ranging from 70,000 to 85,000 psi (480 to 585 MPa), along with high ductility and toughness. It features smooth arc characteristics and excellent fusion in both MIG and TIG processes, producing minimal spatter. ERNiCu-7 guarantees stable mechanical properties and high-quality welds on both base metals and dissimilar joints.

AWS Class ERNiCu-7 MIG and TIG filler metal wire and rod are commonly utilized in welding nickel-copper alloys like Monel® 400 and similar grades. It’s especially well-suited for applications exposed to seawater, such as marine structures, desalination systems, ship hulls, and offshore platforms. Additionally, ERNiCu-7 finds its place in the chemical and petrochemical industries for tanks, piping systems, and heat exchangers that handle acidic or caustic media. It also excels at overlaying carbon steels with a corrosion-resistant layer. The alloy’s resistance to cavitation and stress corrosion makes it perfect for components in high-stress, corrosive environments.
We provide high-quality electrodes, filler wire, MIG and TIG welding wires to a wide range of industries, including oil and gas, food, marine, petrochemical, power generation, and aerospace.
