What is AWS Class ERCu MIG & TIG?
AWS Class ERCu welding wires, used in MIG and TIG applications, are primarily composed of copper with small amounts of phosphorus and other trace elements to enhance conductivity and corrosion resistance. They exhibit excellent mechanical properties, including high tensile strength, good ductility, and superior fatigue resistance. These wires provide reliable weldability, minimal porosity, and strong joint integrity, making them ideal for joining copper and copper-alloy components. Their combination of strength, flexibility, and conductivity ensures consistent performance in electrical, plumbing, and industrial applications where durable, high-quality welds are essential.
