AWS Class ERCuNi is a copper-nickel alloy filler metal that primarily consists of copper (around 70%) and nickel (about 30%), with trace amounts of iron and manganese to boost strength and corrosion resistance. This alloy is known for its exceptional resistance to seawater corrosion, erosion, and biofouling, while also offering solid mechanical properties. It boasts high ductility, tensile strength, and toughness, maintaining stability in both high-temperature and cryogenic environments. The balanced composition of ERCuNi guarantees reliable weld integrity, even in challenging thermal and corrosive conditions.
