AW 5754 H111 is a non-heat-treatable aluminium-magnesium alloy known for its excellent corrosion resistance, good weldability and reliable forming performance. It belongs to the 5000 series aluminium alloys and is commonly used in marine, automotive, chemical, food processing and industrial applications.
If you are looking for an aluminium grade that performs well in harsh environments without sacrificing workability, AW 5754 H111 is one of the most practical options.
Understanding the Name: AW 5754 H111
The name AW 5754 H111 may look technical, but each part has a clear meaning.
- AW stands for aluminium wrought alloy under the European EN standard system.
- 5754 identifies the specific aluminium alloy, mainly alloyed with magnesium.
- H111 refers to the temper condition, meaning the material has been annealed and slightly strain-hardened during processing.
In simple terms, AW 5754 H111 is an aluminium alloy with medium strength, high corrosion resistance and good formability.
Chemical Composition of AW 5754 H111
The main alloying element in AW 5754 is magnesium, which improves strength and corrosion resistance.
| Element | Typical Content |
| Aluminium | Balance |
| Magnesium | 2.6% – 3.6% |
| Manganese | Up to 0.50% |
| Iron | Up to 0.40% |
| Silicon | Up to 0.40% |
| Chromium | Up to 0.30% |
| Zinc | Up to 0.20% |
| Copper | Up to 0.10% |
| Titanium | Up to 0.15% |
Because of its magnesium content, AW 5754 has stronger resistance to seawater and industrial atmospheres than many standard aluminium grades.

What Does H111 Temper Mean?
The H111 temper means the aluminium has been slightly strain-hardened after annealing, usually during flattening or stretching operations.
Compared with fully annealed material, H111 offers slightly improved strength while still keeping good ductility and formability. This makes it suitable for bending, cutting, rolling and welding.
H111 is often chosen when the material needs to be easy to process but still strong enough for structural or semi-structural use.
AW 5754 H111 Characteristics
Corrosion Resistance
Performs exceptionally well in marine, coastal and industrial environments exposed to moisture, salt spray and chemicals.
Weldability
Suitable for MIG and TIG welding with stable post-weld strength and reliable corrosion resistance performance.
Formability
Easy to bend, stamp, roll and form without cracking, ideal for sheet, plate and complex shaped components.
Strength Balance
Medium strength with excellent ductility, offering a balanced combination of durability and workability.
Lightweight Advantage
Much lighter than steel, helping reduce structural weight in transportation, marine and industrial applications.
Common Applications of AW 5754 H111
Because of its combination of corrosion resistance, weldability and formability, AW 5754 H111 is used in many industries.
Common applications include:
- Marine panels and boat components
- Shipbuilding structures
- Vehicle body panels
- Trailer and truck body parts
- Fuel tanks and storage tanks
- Chemical processing equipment
- Pressure vessels
- Food processing equipment
- Flooring and tread plates
- Architectural panels
- Industrial sheet metal parts
It is especially popular in applications where the material must resist corrosion but also remain easy to weld and shape.
AW 5754 H111 vs Other Tempers
- H111: Balanced strength and formability
- H22 / H24: Higher strength but reduced ductility
- O temper: Maximum softness and formability
H111 is commonly selected for welded structures where both strength and fabrication performance are required.
AW 5754 H111 vs 5083 Aluminium
AW 5754 H111 and 5083 aluminium are both 5000 series aluminium-magnesium alloys, but they are not the same.
5083 generally has higher strength and is widely used in heavy marine and structural applications. AW 5754 H111 has slightly lower strength but better formability and is easier to process in many sheet applications.
Choose 5083 when higher strength is the priority.
Choose AW 5754 H111 when corrosion resistance, bending and general fabrication are more important.
AW 5754 H111 vs 5052 Aluminium
5052 and AW 5754 are similar in many ways. Both offer good corrosion resistance and weldability.
However, AW 5754 usually provides better strength than 5052 while still maintaining good formability. For this reason, AW 5754 H111 is often preferred for automotive, marine and industrial sheet applications.
Is AW 5754 H111 Heat Treatable?
No. AW 5754 H111 is a non-heat-treatable aluminium alloy.
Its strength is improved mainly through strain hardening rather than heat treatment. This is typical for 5000 series aluminium alloys. If your project requires a heat-treatable aluminium alloy, grades such as 6061 or 6082 may be more suitable.
Machining and Fabrication
AW 5754 H111 is suitable for many fabrication processes, including:
