ER2319 is a high-copper, manganese-controlled aluminium welding wire designed for heat-treatable 2000-series alloys (e.g., 2219) and Al-Cu castings. Elevated Cu content enhances strength and ductility post-weld heat treatment (PWHT), outperforming 4xxx fillers. Controlled Mn ensures stress corrosion cracking resistance and high-temperature stability. Ideal for aerospace structures, elevated-temperature components, and cast parts (319.0, 355.0, etc.), it delivers optimized mechanical properties in PWHT conditions. Suitable for critical joints requiring balanced strength, crack resistance, and thermal resilience.
