ER 2319| AlCu6MnZrTi

ER2319 is an aluminum welding wire with an elevated copper content （6%）and a controlled manganese. It is heat treatable and produces higher strength and ductility than the 4xxx series filler alloys when welds in 2014, 2036, 2219 and Al-Cu casting alloys are post welds heat-treated.

Mechanical properties

Key Features

• High Strength: 6% copper aluminum filler metal, delivering high-strength welded joints for load-bearing structures.
• Corrosion Resistance: Excellent seawater and environmental corrosion resistance, suitable for marine and chemical applications.
• Processing Adaptability: Good bendability and fracture toughness for complex welding and forming.
• Heat Treatable: Can be further strengthened via heat treatment, ideal for aerospace applications.

Application

• Aerospace: Welding of aircraft and spacecraft components (e.g., fuselage frames, engine parts).
• Marine Engineering: Seawater-resistant hull structures and offshore equipment.
• 2XXX Series Aluminum: Specifically designed for welding/repairing 2000 series alloys (e.g., 2219, 2014).
