Magnesium metal is used in specialized filler wire electrodes—primarily alloys like AZ61A, AZ92A, and EZ33A—for welding magnesium-based components, commonly in aerospace and automotive industries. These filler rods are used in GTAW (TIG) and GMAW (MIG) processes for their excellent strength-to-weight ratio, high thermal conductivity, and good corrosion resistance. The most used filler metals are AZ31B (general welding), AZ61A (higher strength), AZ92A (excellent castability), and EZ33A (high-temperature resistance). Magnesium filler wires and dust are highly flammable and require specialized safety protocols Primarily used for aerospace components, engine parts, structural repairs, and high-strength applications where weight reduction is crucial.
