Durable ERCuNi MIG/TIG Welding Rod for Desalination and Chemical Processing Industries

Our Durable ERCuNi MIG/TIG Welding Wire is built to tackle the toughest welding challenges in desalination, chemical processing, and beyond. This high-strength wire is crafted for joining copper-nickel (CuNi) alloys like 70/30 and 90/10, delivering welds that stand up to corrosion, high temperatures, and harsh environments. Meeting AWS A5.7 and ASME SFA A5.7 standards, it’s a reliable choice for industries where failure isn’t an option.

The wire’s composition—primarily copper with ~30% nickel, plus small amounts of manganese, iron, and titanium—gives it a unique edge. It boasts a tensile strength of around 80,000 psi and 30% elongation, ensuring welds that are both strong and flexible. Whether you’re using MIG (GMAW) for high-speed production or TIG (GTAW) for precision work, our ERCuNi wire delivers clean, consistent results. Its melting range of 1290–1350°C and density of 8.84 g/cm³ make it a stable performer, while its 30% IACS electrical conductivity suits applications needing efficient current transfer.

For steel overlays, we recommend a nickel alloy barrier layer with MIG welding to ensure a robust bond. This wire’s standout feature is its exceptional resistance to saltwater, chemicals, and pitting corrosion, making it a top pick for desalination plants, chemical reactors, and marine systems. It’s not just a welding wire—it’s a solution for projects that demand durability and reliability.
