5754 H22 Aluminum Plate Sheet

5754-H22 aluminum alloy refers to 5754 aluminum alloy that has undergone strain hardening and partial annealing. In this condition, its strength is about one-quarter of the fully annealed (O temper) and fully hardened (H28) tempers. Strain hardening provides strength to the aluminum alloy, while partial annealing helps balance strength and formability, making it suitable for applications requiring high strength and moderate ductility.

5754 aluminum alloy has excellent corrosion resistance, especially suitable for seawater and industrial environments. Its strength is higher than that of 5251 aluminum alloy, making it ideal for flooring applications.

H22 – Obtained by cold rolling followed by annealing to a quarter-hard temper.

5754 h22 aluminum sheet

The magnesium content of 5754 H22 aluminum plate is 2.6% to 3.6%. Its hardness is at a medium level among the 5000-series aluminum plates. The hardness of H22 is equivalent to 25% of the hardness of partially annealed aluminum plates, while the hardness of H32 corresponds to 25% of the hardness of fully annealed aluminum plates. In theory, although H32 and H22 have similar hardness, H32 exhibits more stable mechanical properties.

5754 H22 aluminum alloy, with its balanced mechanical properties, excellent corrosion resistance, and good processing and weldability, is an ideal choice for lightweight structural components. In automotive, marine, and construction fields, it can meet strength requirements while maintaining long-term reliability in harsh environments, making it a highly cost-effective engineering material.

5754 Aluminum

Series: 5xxx series, where the primary alloying element is magnesium (Mg).

Features:

Excellent corrosion resistance: particularly good resistance to seawater corrosion in marine and chemical environments.
Medium strength: higher than 1xxx and 3xxx series pure aluminum and soft-temper aluminum.
Good weldability: compatible with various conventional welding methods, with stable joint performance after welding.
Good processing performance: easy to stamp, draw, bend, and perform other cold-working operations.

H22

"H" indicates a strain-hardened temper. The following digits have specific meanings:

The first digit "2": indicates that after strain hardening, the material has undergone partial annealing.

Full annealing (O temper) makes the material very soft.

Partial annealing only partially removes the internal stresses caused by strain hardening, allowing the material to retain some strength while restoring partial ductility, making it more suitable for further cold working.

The second digit "2": indicates that the final hardness level is quarter-hard.

Therefore, the full meaning of the H22 temper is:

After strain hardening, the material undergoes partial annealing, resulting in a quarter-hard temper.

Features of H22 temper:

Strength: Between fully annealed (O temper) and full-hard (H18), classified as medium strength.
Formability: Much better than fully hardened material, suitable for bending at 90 degrees or larger angles without cracking.
Balance: Achieves an excellent balance between strength and formability, which is why it is widely used.

Corrosion Resistance of 5754 H22 Aluminum

5754 H22 is one of the best-performing alloys in the 5xxx series in terms of corrosion resistance, suitable for structural and decorative components exposed long-term to moisture, salt spray, and marine environments.

Corrosion resistance performance of 5754 H22 aluminum (key points)

Atmospheric corrosion (Excellent)

Very good resistance to general industrial atmosphere, marine atmosphere, and humid environments.

The oxide film is stable and strongly adherent, providing long-term surface protection against corrosion.

Seawater and salt spray environments (Very Good)

The moderate Mg content provides strong pitting corrosion resistance, making it highly suitable for seawater contact.

Commonly used for ship decks, bulkheads, and marine equipment housings.

Resistance to stress corrosion cracking (Better than 2xxx/7xxx)

5xxx-series aluminum alloys are not sensitive to stress corrosion cracking and have good SCC resistance.

Suitable for load-bearing and welded structural components without easily forming cracks.

Good corrosion resistance in welded areas

Unlike heat-treatable aluminums such as 6061, 5754 does not show significant corrosion weakening in the heat-affected zone after welding.

Typical applications of 5754 H22 in corrosive environments

Application	Corrosion resistance advantages
Shipbuilding	Strong resistance to seawater corrosion, not prone to pitting
Automotive fuel tanks and fuel lines	Resistance to chemical media corrosion
Pressure vessels	Stable corrosion resistance after welding
Coastal architectural panels	Resistant to salt spray and atmospheric corrosion
Food and chemical containers	Good resistance to most weak acids and weak alkalis

Possible corrosion issues to consider for 5754 H22 aluminum

Although its corrosion resistance is excellent, the following conditions should be avoided:

Long-term exposure to high temperatures (>65–120°C) may cause intergranular corrosion (IBC)

Reason: Mg supersaturation in solid solution and β-phase precipitation.

Prevention: avoid long-term high-temperature use or select a suitable temper.

Direct contact with copper or steel → risk of galvanic corrosion

Solution: use insulating gaskets or anti-corrosion coatings.

Limited corrosion resistance in strong acids and strong alkalis

For example: hydrochloric acid and concentrated sodium hydroxide cause rapid corrosion.
