Aerospace Grade Aluminum Wire

Advantages

• Maximum Safety Assurance: Unprecedented traceability and quality control eliminate material-related risk in safety-critical air and space applications.

• Meets Toughness Requirements: Specialized alloys and production methods ensure the weld metal achieves the required toughness for resisting crack propagation.

• Zero Defect Performance: The superior cleanliness guarantees porosity-free, X-ray quality welds essential for critical pressure vessels and structures.

• Custom Alloys: Access to special alloys (e.g., ER2319 for 2XXX base metals) that are often mandatory for aerospace repair and fabrication.

FAQ

• Q: What is the primary aluminum alloy filler metal used for welding 2XXX base metals in aerospace?
• A: ER2319 (Al-Cu) is the standard filler metal used for 2XXX series base metals (like 2219) because it provides a weld deposit that is heat-treatable, allowing the final assembly to achieve the high strength required for airframe structures.

• Q: Why is cleanliness more critical for aerospace welding than for general fabrication?
• A: Contaminants (especially oxides/moisture) lead to porosity. In aerospace, this porosity can drastically reduce the fatigue life and fracture toughness of the structure, leading to catastrophic failure under cyclic loading.
