AWS Class ECuNi Coated Electrodes are a key part of its portfolio, trusted for their excellent weldability, corrosion resistance, and suitability for copper-nickel alloy applications.
AWS Class ECuNi Coated Electrodes are copper-nickel–based electrodes formulated for welding copper-nickel alloys. The typical weld metal contains a balanced proportion of copper and nickel, with small additions of iron and manganese to improve strength and corrosion resistance. These electrodes provide good tensile strength, excellent ductility, and stable mechanical properties. The deposited weld metal offers strong resistance to seawater corrosion, biofouling, and erosion, along with smooth arc characteristics that ensure consistent weld quality and reliable performance in marine environments.
