ERCuNi5Fe1 Copper-Nickel Wire for Corrosion-Resistant Marine Welding

Our ERCuNi5Fe1 copper-nickel Welding Wire is a tough, reliable choice for marine welding. Packed with about 5% nickel and 1% iron, this wire is built to create strong, corrosion-resistant welds that hold up in salty, wet conditions. It’s designed for TIG welding, delivering a smooth arc and clean bead with barely any spatter. Whether you’re working on copper-nickel alloys (like 90/10 or 70/30 Cu-Ni) or joining dissimilar metals, this wire gets the job done, making it perfect for marine pipelines, shipbuilding, and more.

We’ve dialed in our ERCuNi5Fe1 wire to tackle the harshest marine environments. The nickel and iron combo boosts corrosion resistance, especially against seawater, while keeping welds strong with tensile strength around 50,000-60,000 psi. It’s a champ at welding copper-nickel alloys or pairing them with steel, delivering crack-free joints every time. The wire’s smooth feed and stable arc make it a breeze to use, whether you’re welding by hand or with automated systems. It’s built to last in tough conditions like offshore platforms or desalination plants.

Industry Analysis

The copper-based welding wire market is growing fast, projected to reach USD 4.5 billion by 2030 with a 5.5% CAGR. Marine industries, along with chemical and energy sectors, are fueling demand for materials that can handle corrosion in extreme environments. Copper-nickel wires like ERCuNi5Fe1 are a hot commodity for their ability to meet strict marine and safety standards. With offshore wind farms, tidal energy projects, and shipbuilding on the rise, high-performance welding wires are more critical than ever to keep equipment reliable and long-lasting.
