5083 h111 aluminum plate sheet
5083-H111 aluminum plate is a typical 5000 series Al-Mg corrosion-resistant aluminum alloy sheet, with magnesium (approximately 4.0–4.9%) as the main alloying element, supplemented by trace elements such as manganese and chromium to form a high-magnesium alloy. This material is a non-heat-treatable alloy, and its properties are mainly obtained through work hardening. It has extensive application value in marine grade aluminum plates and welded structural fields.
H111 is a common supply temper of the 5083 alloy, indicating that the sheet has only undergone light strain hardening after final annealing, with a lower degree of work hardening than the H11 temper requirement. This temper achieves a good balance between strength and formability: compared with the O temper, it has higher mechanical strength while still maintaining excellent ductility and processing adaptability, suitable for bending, forming, and subsequent structural manufacturing. Therefore, 5083 H111 aluminum sheet is often regarded as an ideal material choice for general-purpose medium-strength welded structures.
As one of the marine-grade aluminum alloys, 5083 H111 exhibits outstanding corrosion resistance, especially stable performance in seawater or high-humidity salt spray environments, effectively reducing long-term maintenance costs. At the same time, it has excellent weldability, with reliable welded joint quality, and is widely used in shipbuilding, pressure vessels, transportation equipment, and engineering structures.
In terms of temper performance comparison:
- Compared with H116: strength and corrosion resistance are slightly lower, but plasticity and formability are better
- Compared with O temper: strength is significantly improved
- Suitable for applications emphasizing processing and bending performance rather than ultimate strength
5083-H111 aluminum alloy plate combines corrosion resistance, weldability, and moderate strength, making it a reliable material option that balances processing flexibility and durability in marine aluminum sheets, structural plates, and general manufacturing fields.

Aluminium 5083 H111 Features
5083 H111 aluminum is a typical Al-Mg corrosion-resistant alloy and a non-heat-treatable material. The H111 temper represents light work hardening while maintaining high ductility, thus achieving a good balance between strength, formability, and corrosion resistance. It is widely used in marine aluminum plates, shipbuilding aluminum, and cryogenic tank materials. Its main performance features are as follows:
Excellent Corrosion Resistance
Thanks to its high magnesium content, 5083 H111 exhibits strong corrosion resistance in seawater, marine atmospheres, and industrial chemical environments. It is especially suitable for structural components exposed long-term to humid and high-salt environments, making it a typical marine-grade aluminum.
Moderate Strength with High Ductility
Compared with stronger tempers such as H116, H111 has slightly lower strength but is still significantly higher than pure aluminum and 1xxx/3xxx series alloys. At the same time, it retains plasticity close to the annealed state, suitable for stamping, bending, cold forming, and other complex forming requirements. It usually meets the balance of strength and workability required for most non-heavy-duty structural applications.
Excellent Forming and Machining Performance
The H111 temper has good cold working adaptability, suitable for shearing, stamping, rolling, and structural processing, improving manufacturing efficiency and reducing the risk of processing cracks.
Stable Low-Temperature Performance
5083 does not become brittle at low temperatures; instead, it maintains or even increases strength and toughness. It remains reliable under extremely low-temperature conditions (such as liquefied gas storage and transportation equipment), making it commonly used in cryogenic aluminum applications.
Non-Heat-Treatable Strengthening
As a non-heat-treatable alloy, its strength improvement relies mainly on work hardening rather than quenching and aging, meaning the material structure is stable and performance fluctuations during service are minimal, suitable for long-term service environments.
5083 H111 Aluminum Plate Corrosion Resistance
5083 H111 aluminum plate is a typical Al-Mg high-magnesium corrosion-resistant aluminum alloy, known for its excellent corrosion resistance. Its high magnesium content provides outstanding resistance in seawater, humid marine atmospheres, and industrially polluted environments, effectively resisting pitting and long-term corrosion. Therefore, it is widely used in marine aluminum plates, shipbuilding materials, and offshore structures.
In practical engineering applications, the corrosion resistance of 5083 alloy is a key reason for its adoption in shipbuilding and marine engineering. Whether used for hull structures, deck components, or offshore equipment, it maintains stable performance and a long service life in high-salt spray environments.
It should be noted that different tempers emphasize corrosion resistance differently. In addition to the H111 temper, 5083-H116 and 5083-H321 aluminum plates undergo stabilization treatment, showing particularly excellent performance in exfoliation corrosion resistance and stress corrosion cracking resistance, suitable for more severe marine service conditions.
With its stable and reliable corrosion resistance, 5083 H111 aluminum plate has become a common and mature marine-grade aluminum solution in shipbuilding and marine engineering.
