5754 H111 Aluminum Plate Sheet

5754 H111 aluminum plate refers to sheet made from aluminum alloy 5754, subjected to strain hardening and then annealed to achieve H111 temper. This temper is typically used for applications requiring strength and corrosion resistance, such as in the marine and automotive industries.

The forming process of 5754 H111 Aluminum provides a certain degree of work hardening, albeit less than what is required for the H11 temper.

5754 H111 aluminum is a typical representative of the Al-Mg anti-rust aluminum alloys, featuring medium strength, excellent corrosion resistance, and good weldability. It is suitable for automotive manufacturing, ship structures, pressure vessels, etc. Its density is 2.8 g/cm³. The main alloying elements are magnesium (2.6%–3.6%) and manganese (0.5%).

5754 aluminum sheet

The H111 temper of 5754 aluminum makes it an ideal choice for manufacturing complex welded structural components because it can withstand a certain load while allowing easy bending and forming during manufacturing, ensuring dimensional stability and corrosion-resistance durability.

5754: The grade of the aluminum-magnesium alloy, which specifies its main chemical composition.
H111: The designation of its strain-hardened temper, indicating that it has undergone a certain amount of work hardening followed by appropriate annealing to achieve specific mechanical properties.

With its combined advantages of “corrosion resistance + weldability + medium strength, ” 5754 H111 aluminum alloy has become a preferred material in marine, automotive, and construction industries. Its H111 temper balances strength and formability, making it suitable for structural parts that require frequent welding or forming. In practical applications, the temper should be selected according to specific working conditions (e.g., H112 for higher load-bearing), and processing and welding procedures must be strictly controlled to ensure performance.

5754 Aluminum

5754 is an Al-Mg series alloy and belongs to anti-rust aluminum. Its main characteristics are as follows:

Main alloying element: magnesium, with a content of approximately 2.6–3.6%. The addition of magnesium significantly increases the strength of aluminum while maintaining good corrosion resistance and weldability.

Significant features:

Medium strength: Higher than pure aluminum and the 1xxx series, but lower than the high-strength 2xxx or 7xxx series.
Excellent corrosion resistance: Particularly good resistance to seawater corrosion in marine and chemical environments.
Excellent weldability: Compatible with multiple welding methods (e.g., MIG, TIG), with stable welded joints and corrosion resistance close to that of the base metal.
Good formability: Suitable for stamping, bending, and other processes.
Non-heat-treatable strengthening: It cannot achieve significant strengthening through “quenching + aging” heat treatment like 6061; its strength mainly comes from cold working (work hardening).

Comparison with similar grades of 5754:

5754 vs 5052: 5754 generally has a slightly higher magnesium content than 5052 (2.2–2.8% Mg), and therefore its strength is also slightly higher. Both can be interchangeable in many applications, but 5754 is more common in European standards.

Temper: H111

“H” stands for “strain-hardened.” H111 is a specific branch of the H1x tempers.

H1x: Strength is increased solely through strain hardening.

The last digit “1” indicates that a final annealing process has been performed. However, this annealing is not full softening (as in the O temper), but a partial or stabilizing anneal.

The specific meaning of H111:

First, the material undergoes a certain degree of cold working (rolling, drawing, etc.), giving it greater strength than the O (annealed) temper.

Then, a low-temperature annealing is performed to eliminate internal stress, improve dimensional stability, and enhance formability. This treatment does not fully soften the material, but allows it to retain higher strength while offering better ductility, preventing cracking during subsequent forming (such as bending).

Simply put, the H111 temper lies between the “fully annealed (O temper)” and the “fully hardened (such as H14)” conditions. It has a certain level of strength while maintaining good formability.

Comparison of 5754 H111 with other tempers:

H112: Hot-worked and naturally cooled, with higher strength, suitable for high-load structural components.
O temper: Fully annealed, with the lowest strength but the best ductility.

Advantages of 5754 H111 Aluminum

Corrosion resistance: Magnesium forms a dense oxide film; it is especially resistant to seawater, industrial pollution, and chloride stress corrosion cracking, with performance superior to 3-series aluminum-manganese alloys.
Weldability: Suitable for gas-shielded welding (MIG/TIG) and arc welding, with minimal post-weld strength loss; weld corrosion resistance is close to that of the base material.
Workability: Slight cold-working retained after annealing (H111 temper), combining medium strength with good ductility, suitable for deep drawing, bending, and other complex forming processes.
