What is AWS Class ERCuSi-A MIG and TIG Filler Metal?

The AWS Class ERCuSi-A MIG and TIG filler metal is mainly made up of copper (Cu) with 2.8–4.0% silicon (Si) and trace amounts of manganese (Mn). This unique blend offers fantastic corrosion resistance, good electrical conductivity, and remarkable thermal properties. In terms of mechanical characteristics, it boasts a tensile strength of about 50,000 psi (345 MPa) and an elongation of roughly 30%. The alloy is known for its excellent weldability, minimal spatter, and smooth bead appearance, making it a great fit for both MIG and TIG welding in various industrial environments.
