AW 5754 H111 vs H22: Strength, Formability, Bending and Applications

If you are sourcing EN AW-5754 aluminum sheet or plate, the alloy number is only part of the decision. The temper matters just as much. Two common options are 5754 H111 and 5754 H22. They are made from the same aluminum-magnesium alloy, but they do not behave the same in fabrication or service.

In simple terms, 5754 H111 is usually softer and easier to form, while 5754 H22 is stronger, harder and more resistant to dents. That difference can affect bending radius, forming quality, panel flatness, weld fabrication and the long-term performance of the final part.

Choose 5754 H111 when the part needs better bending, rolling, forming or welding flexibility.
Choose 5754 H22 when the part needs higher strength, better surface hardness and improved resistance to deformation.

What Is EN AW-5754 Aluminum?

EN AW-5754 is a 5xxx series aluminum alloy. Its main alloying element is magnesium, which gives the material a useful balance of corrosion resistance, strength, weldability and workability. It is not a heat-treatable alloy, so its mechanical properties are mainly adjusted through work hardening and annealing processes.

5754 aluminum is widely used where moderate-to-high strength and good corrosion resistance are required. It performs well in many industrial, marine and transportation environments. Compared with some 6xxx series alloys, 5754 is often selected when welding performance and corrosion resistance are more important than high machinability.

What Do H111 and H22 Mean in 5754 Aluminum?

What Does H111 Mean in 5754 H111?

The H111 temper means the material has been annealed and then lightly strain-hardened during final operations such as stretching, flattening or shaping. It is not as hard as standard strain-hardened tempers such as H22 or H32.

In real workshop conditions, 5754 H111 is known for easier fabrication. It is generally more forgiving when the part needs to be bent, rolled, pressed or welded into a more complex shape. If a drawing includes curved areas, flanges or multiple forming steps, H111 is often a safer starting point than a harder temper.

Main characteristics of 5754 H111

Lower strength than 5754 H22
Better ductility and formability
Easier bending with a lower risk of cracking
Good weldability
Excellent corrosion resistance
Suitable for formed, rolled and fabricated parts

For example, if a fabrication shop is making curved marine panels, shaped covers, welded tank parts or components that require several bending operations, 5754 H111 is commonly chosen because it gives the operator more forming margin.

What Does H22 Mean in 5754 H22?

The H22 temper is strain-hardened and then partially annealed. This gives the material higher strength and hardness than H111, while still keeping a level of workability suitable for many sheet and plate applications.

In practical use, 5754 H22 is selected when the final part needs better strength, dent resistance and shape stability. It is often used for panels, covers, floors and components that should stay flat and resist visible deformation during handling or service.

Main characteristics of 5754 H22

Higher tensile strength than H111
Higher yield strength than H111
Better resistance to dents and surface deformation
Better panel stability in many flat-sheet applications
Good weldability
Excellent corrosion resistance
Lower formability than H111, especially for tight bends

H22 is a practical choice for truck body panels, trailer side panels, machine covers, industrial enclosures, flooring plates and other parts where the material should resist bending or denting after installation.

Mechanical Properties: How Different Are They?

Exact mechanical values depend on thickness range, production standard, mill process and certificate requirements. For engineering use, the mill test certificate and the applicable standard should always be checked before final approval.

As a general guide, 5754 H111 has lower yield strength and better elongation, while 5754 H22 has higher yield strength and tensile strength but lower ductility. This is the reason H111 is usually easier to form and H22 is usually better for stronger, flatter panels.

Property	5754 H111	5754 H22	Practical Meaning
Tensile strength	Typically lower than H22	Typically higher than H111	H22 can carry more stress before failure
Yield strength	Lower	Higher	H22 resists permanent deformation better
Elongation	Usually higher	Usually lower	H111 has better forming margin
Hardness	Lower	Higher	H22 has better dent and handling resistance
Fabrication behavior	More forgiving	Requires more attention to bend radius and forming direction	H111 is often easier in complex fabrication

Which Is Better for Bending: 5754 H111 or H22?

For bending, 5754 H111 is generally the better choice. Because it is softer and more ductile, it can normally tolerate tighter bends with a lower risk of cracking. This matters when the part has flanges, curved edges, rolled sections or multiple forming operations.

5754 H22 can still be bent, but it normally needs more attention. A larger inside bend radius may be required, and the bending direction relative to the rolling direction can affect the result. If a tight bend is required, sample testing is strongly recommended before ordering a large quantity.

Choose 5754 H111 for bending when:

The part has tight bends or smaller bend radii
The design includes curved or rolled sections
The part requires several forming operations
The fabrication shop wants a more forgiving material
Cracking during bending would cause high scrap cost

Choose 5754 H22 for bending only when:

The bend radius is not too tight
The part mainly needs strength after bending
The forming process has already been tested
The drawing allows enough forming tolerance
The supplier and fabricator agree on suitable processing conditions

Welding Performance of 5754 H111 vs H22

Both 5754 H111 and 5754 H22 offer good weldability. This is one reason 5754 aluminum is popular in marine, tank, vehicle and industrial fabrication. MIG and TIG welding are commonly used depending on part thickness, joint design and production requirements.

However, welding can change the mechanical properties in the heat-affected zone. This is especially important when the design depends on the higher strength of H22. After welding, the local strength around the weld area may not be the same as the original base material condition.

For heavily welded structures, the difference between H111 and H22 should be reviewed with the design engineer. In many fabricated assemblies, the ease of forming and fit-up may make H111 more practical. In other cases, H22 may still be selected for areas away from the weld or for panels that need better dent resistance.

Corrosion Resistance: Is There a Difference?

Since both tempers are based on the same EN AW-5754 alloy, their corrosion resistance is broadly similar. The main difference between 5754 H111 and H22 is mechanical behavior, not corrosion resistance.

5754 aluminum has good resistance in many marine and industrial environments. It is commonly used for boat parts, ship structures, wet-area components, tank bodies and outdoor equipment. Surface finish, cleaning, installation details and contact with dissimilar metals can still influence long-term performance.

To improve corrosion performance in real applications:

Avoid direct contact with incompatible metals without insulation
Use suitable fasteners for aluminum structures
Prevent water traps in the design
Clean salt, chemicals and dirt from exposed surfaces when necessary
Consider anodizing, coating or painting when the environment requires extra protection

5754 H111 vs H22 for Marine Applications

Both 5754 H111 and H22 can be used in marine-related applications, but they are not always used for the same type of part.

5754 H111 is often preferred for marine parts that need forming, welding or fitting into curved structures. It is easier to shape and can reduce the risk of cracking during fabrication. This makes it useful for boat panels, formed brackets, curved covers and welded marine components.

5754 H22 may be preferred for flatter marine panels, covers, deck-related parts or areas where better dent resistance and higher strength are useful. It is a good option when the part does not require severe forming.

Marine Part Type	Recommended Temper	Reason
Curved boat panels	5754 H111	Better formability and easier shaping
Welded marine structures	5754 H111 or project-specific	Good fabrication behavior; welding design should be checked
Flat covers and protective panels	5754 H22	Better dent resistance and panel stability
Deck or flooring plates	5754 H22 or tread plate temper specified by project	Higher surface hardness and resistance to deformation may be useful

5754 H111 vs H22 for Vehicle and Trailer Panels

For vehicle body panels, trailer side panels, truck bodies and protective covers, 5754 H22 is often a strong candidate. Its higher strength and hardness help reduce visible dents and improve shape stability during service.

In transportation applications, sheets may experience vibration, loading, unloading, handling impact and weather exposure. H22 can help the panel maintain a cleaner appearance and resist minor deformation better than H111.

That said, if the vehicle panel requires complex forming or tight bends, H111 may still be more suitable. The final choice should be based on the drawing, bend radius, tooling, thickness and appearance requirements.

5754 H111 vs H22 for Flooring and Tread Plate

Aluminum flooring and tread plate applications usually need a combination of corrosion resistance, slip resistance, stiffness and durability. In many cases, a stronger temper such as H22 can be useful because the surface must resist wear, denting and repeated loading.

However, flooring parts sometimes require bending at edges or forming into trays, ramps or special profiles. If the design includes significant forming, the bendability of H111 can be an advantage.

For flooring projects, the best approach is to review not only the alloy and temper, but also the plate thickness, pattern height, support spacing and loading condition.

How to Choose Between 5754 H111 and H22

The right temper depends on how the material will be processed and how the final part will work in service. Before purchasing, ask three questions:

Will the sheet or plate be bent, rolled, pressed or deeply formed?
Does the final part need higher strength and better dent resistance?
Will the component be welded, and does the design depend on strength near the weld?

5754 H111 is better when fabrication comes first

Better for bending and forming
More suitable for curved parts
Useful for welded assemblies
Lower risk of cracking during tight bends
Good choice for marine fabrication and shaped components

5754 H22 is better when strength comes first

Higher strength than H111
Better resistance to dents
Better for flat panels and covers
Useful for truck bodies, trailers and industrial panels
Good choice when severe forming is not required

When comparing AW 5754 H111 vs H22, the best choice depends on the balance between fabrication and final strength. Both tempers offer good weldability and excellent corrosion resistance because they are based on the same 5754 aluminum alloy. The difference is mainly in strength, hardness, ductility and forming behavior.

If the part needs bending, rolling, shaping or easier weld fabrication, 5754 H111 is usually the safer option. If the part is mostly flat and needs better strength, dent resistance and panel stability, 5754 H22 is often the better choice.

For important projects, do not choose by alloy name alone. Confirm the drawing, thickness, bend radius, welding plan, surface requirement and mechanical properties before placing the order. A short discussion with the supplier and a small sample test can prevent expensive production problems later.
