5083 h111 aluminum plate sheet
5083-H111 is a temper of the 5083 aluminum alloy, where the metal undergoes strain hardening to achieve strength lower than the H11 state (1/8 hardness).
What material is 5083 H111?
5083-H111 is an aluminum alloy that combines excellent seawater corrosion resistance, weldability, moderate strength, and good formability.
5083-H111 refers to 5083 aluminum alloy in the H111 temper. This temper involves annealing and slight strain hardening to improve strength and formability. It is a non-heat-treatable alloy, commonly used in shipbuilding, rail vehicles, automotive body panels, and pressure vessels.
The H111 temper indicates that the material has undergone a certain degree of strain hardening through forming (or plastic deformation), but less than what is required for the H11 temper. It achieves a balance: the strength is higher than the fully annealed ("O") state, yet the formability and weldability are better than the higher hardness tempers.
Meaning of H111:
- It indicates that the material has undergone some work hardening, but the hardening level is insufficient to reach the H11 temper.
- Subsequently, a low-temperature annealing process is applied to partially relieve internal stresses, making its strength slightly lower than the H11 temper.
- The H111 temper can be understood as a "semi-hard" or "stabilized" state. It is harder and stronger than the fully annealed O temper, yet softer than fully hardened tempers like H14, offering better formability.
Characteristics of H111:
- Good balance of strength and formability: It provides moderate strength while allowing reasonable bending, stretching, and other forming operations.
- Low internal stress: Compared to higher work-hardened states, its internal stresses are partially relieved, reducing deformation tendencies after processing.

5083 H111 vs H116
Production Process Differences
5083 H111
Suitable for products that have undergone sufficient work hardening but whose hardening level does not fully meet the H11 requirements. This temper is achieved by applying sufficient work hardening without reaching the full annealed state, but the hardening does not completely match the H1 temper.
5083 H116
Specifically suitable for 5xxx series alloys with magnesium content ≥3%. This is a special strain hardening treatment, where temperature is precisely controlled to enhance the corrosion resistance of the aluminum-magnesium alloy. H116 is a special heat-treated temper, between H112 and H321, optimizing corrosion resistance and strength.
It can be seen that the strength of 5083 H116 is significantly higher than H111, but its elongation is lower, making the material relatively harder and more brittle.
Corrosion Resistance Comparison
In terms of corrosion resistance, H116 is clearly superior to H111:
- H116 has excellent resistance to exfoliation corrosion, with exfoliation corrosion rating ≤ PB
- Intergranular corrosion value of H116 ≤ 15 Mg/cm²
- H111 temper does not have special treatments targeting corrosion resistance
This makes H116 particularly suitable for marine and other harsh corrosive environments.
Application Differences
5083 H111
Suitable for applications requiring good formability and weldability, such as ship hulls and decks, automotive body structural components, etc.
5083 H116
Mainly used for applications in marine environments requiring high corrosion resistance, such as underwater parts of ships, offshore engineering structures, and pressure vessels requiring high strength and corrosion resistance.
What is the difference between 5083 H116 and 5083 H321?
Production Process Differences
5083 H116
A special temper designed for 5xxx series alloys with magnesium content ≥3%, using controlled temperature strain hardening to enhance corrosion resistance.
5083 H321
Suitable for products that have undergone rolling work hardening followed by low-temperature heat treatment or mechanical property stabilization due to thermal effects during hot processing. H321 is a stabilized temper after cold working, typically improving ductility.
In some cases, H321 can be used interchangeably with H111 and H116, and it is considered a marine-grade material.
The strength range of H321 is relatively wide; the lower limit is comparable to H116, but the upper limit is higher, and elongation is also slightly greater, indicating better overall performance.
Corrosion Resistance Comparison
In terms of corrosion resistance:
- H116 has excellent resistance to exfoliation corrosion, with an exfoliation corrosion rating ≤ PB
- Intergranular corrosion value of H116 ≤ 15 Mg/cm²
- H321 also has good corrosion resistance, but the standards do not explicitly specify its exfoliation corrosion performance
Both tempers are suitable for marine environment applications requiring high corrosion resistance.
Application Differences
5083 H116
Mainly used in marine environments with extremely high corrosion resistance requirements, such as underwater parts of ships and offshore engineering structures.
5083 H321
Suitable for applications requiring high strength and good weldability, such as pressure vessels, tanker trucks, refrigerated trucks, and refrigerated containers.
H321 is an ideal choice for marine aluminum plates because it maintains excellent tensile strength in welded areas.
5083 H111 vs H112
- H111 has a lower degree of work hardening, suitable for scenarios requiring moderate strength.
- H112 is suitable for hot-formed products with stricter mechanical property requirements.
5083 Aluminum Selection Recommendations
5083 H111 aluminum alloy, as a high-strength, corrosion-resistant Al-Mg series alloy, offers excellent overall performance, especially in marine environments and applications requiring lightweight structures.
- When good formability and weldability are required, prioritize the 5083 H111 temper
- When higher strength and superior corrosion resistance are needed, consider the 5083 H116 temper
- When high strength and good weldability are required, the 5083 H321 temper can be considered
- In marine environments, especially for parts exposed to seawater, H116 or H321 tempers of 5083 aluminum should be prioritized
