Both QQ-A-250/30 bare plate and AMS 4094 clad plate are aerospace-grade 2219 aluminum, but they are designed for different needs. Understanding the difference helps you select the right option for your project.
Instant Quote| Feature | Bare 2219 (QQ-A-250/30) | Clad 2219 (AMS 4094) |
| Surface | Uncoated 2219 aluminum alloy | Thin layers of pure aluminum bonded to both sides |
| Strength | Maximum strength of 2219 core | Slightly lower effective strength (small pure Al layers) |
| Corrosion resistance | Lower; requires coatings/paint for long-term exposure | High; Alclad skin forms protective oxide even if scratched |
| Typical applications | Internal parts, coated components, machined aerospace structures | Aircraft skins, cryogenic fuel tanks, exterior panels in corrosive environments |
| Cost | More cost-efficient | Slightly higher cost due to cladding |
| Specifications | AMS-QQ-A-250/30, AMS 4031 (bare O), AMS 4095/4096 | AMS 4094 (Alclad T81/T851) |
In short: choose bare plate if your part will be coated, machined, or used in a controlled environment; choose clad plate if you need long-term corrosion protection without heavy coatings.

Real-world application cases of 2219 aluminum sheet plate
Fuel Tanks: Wing fuel tanks are part of the wing structure, made from the same material as the wing itself, with the seams sealed using oil-resistant sealants. Due to the advantages of aluminum alloy, such as lightweight, high strength, ease of forming, and ease of welding, it is widely used in fuel tank structures.
Space Boosters: 2219 aluminum was chosen because of its lightweight properties and ability to withstand the pressure generated during space launches and operations. It has been used in the Apollo spacecraft, Skylab, the Space Shuttle, and the International Space Station.
Machinability recommendations for 2219 aluminum sheet plate
- This alloy is not suitable for hot working.
- It is best suited for cold working and can be machined in the annealed condition.
- It is recommended to use oil-based lubricants in all machining operations.
- Hot working and welding can adversely affect the corrosion resistance of this alloy.
- It can be machined using conventional methods such as drilling, milling, and turning.
Welding recommendations for 2219 aluminum sheet plate
- Welding can affect the corrosion resistance of 2219 aluminum rods. Therefore, heat treatment should be performed after welding to restore corrosion resistance.

What are the uses of 2219 aluminum alloy?
2219 aluminum is widely used in aerospace and defense applications, especially for cryogenic fuel tanks, high-temperature structural parts, and precision components. It is also applied in automotive racing, marine engineering, and tooling where strength and weldability are critical.
What is 2219 aluminum?
2219 is a high-strength aluminum-copper (Al-Cu) alloy with excellent mechanical properties, fracture toughness, and resistance to stress corrosion cracking. It is known for maintaining performance from -452 °F (-269 °C) up to 600 °F (315 °C), making it ideal for aerospace-grade applications.
How strong is 2219 aluminum?
The typical tensile strength of 2219-T851 plate is about 62 ksi (427 MPa), and yield strength is around 40 ksi (276 MPa). It combines high strength with good toughness and machinability, outperforming many other aluminum alloys in high-temperature service.
Is 2219 aluminum weldable?
Yes. 2219 aluminum is one of the most weldable high-strength aluminum alloys. It has low hot-cracking sensitivity and maintains good mechanical properties across welded joints, which is why it is widely used in aerospace propellant tanks and structural weldments.
