Introduction

The demands of aerospace fabrication necessitate welding materials with absolute consistency, minimal impurities, and predictable performance. Our aerospace-grade wires are produced under an enhanced quality assurance system, exceeding standard industry requirements. These filler metals are tailored for sensitive applications, where weld integrity is non-negotiable and lightweighting is paramount. The composition control minimizes the risk of hot cracking and ensures precise mechanical properties post-weld.

Specification

Classification (AWS)ER2319 / ER4043 / ER5183
Purity LevelControlled trace element limits
Base Metal Compatibility2219, 6061, and various wrought aluminum alloys
Hydrogen ContentExtremely low, certified (to prevent porosity)
PackagingSealed containers with inert atmosphere option

Applications

  • Fabrication and repair of aircraft ground support equipment and components.

  • Welding of complex aluminum alloy assemblies in defense applications.

  • Components requiring high-strength and operating under thermal cycling.

  • Specialized R&D and prototyping involving high-performance alloys (e.g., ER2319).

FAQ

  • Q: What differentiates "Aerospace Grade" wire from standard industrial wire?
  • A: The difference lies primarily in the tighter tolerance on chemical composition, stricter control over impurities (like Fe and Si), and enhanced surface cleaning to achieve near-zero porosity and maximize mechanical performance.
  • Q: Can your specialized ER2319 alloy be heat-treated after welding?
  • A: Yes, the ER2319 filler metal is designed to be heat-treatable and provides weldments that respond to post-weld solution and aging treatments, recovering strength comparable to the base metal.

Advantages

  • Microstructure Homogeneity: Consistent grain structure and chemistry reduce susceptibility to micro-fissures and stress risers in the weld metal.

  • Certified Low Porosity: Strict control over production atmosphere and wire surface cleaning minimizes hydrogen content, crucial for avoiding weld porosity.

  • High Reliability: Comprehensive internal testing and full material traceability from raw billet to final spool ensures predictable performance.

  • Specialized Alloy Availability: Production capability for difficult-to-source, high-performance alloys like ER2319 for 2219 base metal applications.

Payment and Shipping

  • Traceability: Each batch is supplied with detailed certificates of conformance, ensuring 100% material traceability required for QA documentation.

  • Handling: Specialized, protective packaging is used to prevent any surface contamination or damage during transit.

  • Compliance: Adherence to ITAR/export control regulations where required for specific defense-related shipments.
