Aluminum 2219
Aluminum 2219 is a high-strength, heat-treatable aluminum-copper alloy developed for applications requiring excellent weldability and reliable performance at both elevated and cryogenic temperatures. Unlike many high-strength aluminum alloys, Aluminum 2219 retains good mechanical properties after welding.
Because of its combination of strength, weldability, and thermal stability, Aluminum 2219 is widely used in aerospace and space-related applications, including fuel tanks, structural components, and pressure vessels.
While Aluminum 2219 offers good corrosion resistance compared to other copper-containing aluminum alloys, it is still typically used in controlled environments or with protective treatments depending on service conditions.
Aluminum 2219 is commonly supplied in plate, sheet, bar, and forging forms and can be provided to meet aerospace and industry specifications with full material traceability.
Aluminum 2219 FAQ
What is Aluminum 2219 used for?
Aluminum 2219 is commonly used in aerospace and space applications such as fuel tanks, pressure vessels, structural components, and parts that require both high strength and good weldability.
Is Aluminum 2219 weldable?
Yes. Aluminum 2219 is one of the most weldable high-strength aluminum alloys. Unlike alloys such as 2024, it retains much of its mechanical strength after welding and is frequently specified for welded aerospace structures.
Is Aluminum 2219 heat treatable?
Yes. Aluminum 2219 is a heat-treatable alloy and is commonly supplied in tempers such as T6, T87, or T62 depending on application requirements.
How does Aluminum 2219 compare to Aluminum 2024?
Compared to Aluminum 2024, Aluminum 2219 offers:
- Significantly better weldability
- Better performance at cryogenic temperatures
- Slightly lower peak strength
2219 is chosen when welding is required, while 2024 is preferred for non-welded high-strength applications.
Is Aluminum 2219 corrosion resistant?
Aluminum 2219 offers moderate corrosion resistance compared to other aluminum-copper alloys but is typically used with protective coatings or in controlled environments.
