5083 h116 aluminum plate sheet
5083-H116 is a high-strength, corrosion-resistant 5000-series aluminum-magnesium alloy (Al-Mg system). Magnesium is the primary alloying element (content 4.0% – 4.9%), and it also contains manganese, chromium, and other elements. This alloy belongs to the category of non-heat-treatable strengthened materials, with its corrosion resistance and exfoliation corrosion resistance in marine environments enhanced through strain hardening and stabilization treatment (H116 temper).
The H116 temper is specifically designed for high-magnesium alloys. Through special tempering and stabilization treatment, it maintains excellent performance even after long-term exposure to saltwater and hot, humid environments. Compared with the H321 temper, H116 has slightly lower strength but superior corrosion resistance, making it especially suitable for demanding applications such as ships, marine structures, cryogenic tanks, and liquefied natural gas (LNG) storage tanks.
With its high strength, excellent corrosion resistance, good weldability, and low-temperature toughness, 5083-H116 aluminum alloy has become the preferred material for shipbuilding, marine engineering, and other demanding fields. It not only extends structural service life but also balances strength with processing performance, making it the gold standard among high-magnesium aluminum alloy applications.

5083 H116 vs H111
5083 aluminum alloy is a typical aluminum-magnesium corrosion-resistant alloy widely used in shipbuilding, marine engineering, and offshore structures. Among its common marine-grade supply tempers, H116 and H111 differ significantly in strength level, corrosion-resistance certification, and processing characteristics, directly affecting material selection.
Mechanical Properties and Structural Strength
Compared with H111, 5083 H116 plate undergoes more thorough processing and temperature control, resulting in higher strength levels:
- Yield strength: typically about 50% – 70% higher, providing stronger load-bearing capacity
- Tensile strength: overall improvement, more suitable for load-bearing structures
- Applications: suitable for hull plating, value decks, keels, and other load-bearing parts
Meanwhile, 5083 H111 plates have a lower processing temper and milder strength level, providing stronger forming bearing ultimate load capability.
For marine structures requiring a high strength-to-weight ratio, H116 offers added advantages.
Seawater Corrosion Resistance and Certification Differences
Although both tempers belong to marine-grade aluminum 5083, their corrosion-resistance verification levels differ:
5083 H116
- Passes dedicated exfoliation and intergranular corrosion tests
- Controlled for long-term stability of high-magnesium alloys in saltwater environments
- Common in applications requiring classification certification (CCS/DNV/LR, etc.)
5083 H111
- Possesses good natural corrosion resistance
- But cannot meet the same level of exfoliation test requirements
- More suitable for non-critical immersed structures
This makes 5083 H116 marine aluminum plate more reliable in splash zones, near waterlines, or in long-term immersion environments.
How to choose between 5083 h116 and h111?
Prefer 5083 H116 for:
- Hull outer plating
- Offshore load-bearing structures
- Long-term seawater immersion components
- Projects requiring classification certification
Prefer 5083 H111 for:
- Internal structural parts
- Fuel tanks or storage tanks
- Complex curved components
- Scenarios requiring moderate strength but high workability
5083 H116 vs H112
The difference between 5083 aluminum plate H116 and H112 lies not in alloy composition but in processing and stabilization methods, which influence strength level, corrosion resistance, and application environment. Understanding these differences helps make better decisions when selecting marine or structural aluminum plate.
Temper Formation and Material Characteristics
5083 H112 aluminum plate
The H112 temper usually forms through hot working or slight cold working and does not have strictly controlled strengthening levels. The material maintains good ductility and processing tolerance, offering consistency for bending, welding, or subsequent forming. Because its mechanical properties allow some variation, it is often used for general structural parts or as raw material for further processing.
5083 H116 aluminum plate
In contrast, H116 is a stabilized temper designed for marine environments. By controlling the degree of lymphoma processing and property consistency, it provides more reliable resistance to exfoliation and intergranular corrosion. This temper typically meets defined performance standards and is widely evaluated for projects requiring long-term water exposure or classification certification.
These can be understood as having different emphases:
- H112 leans toward processing flexibility
- H116 leans toward stability
Strength and Plasticity Differences
- H116 generally provides higher yield and tensile levels, suitable for load or structural stability requirements
- H112 retains better plasticity and deformation capability, offering more operational flexibility in complex fabrication
Therefore, a balance must be made between enhancing structural load capacity and improving forming convenience depending on project needs.
Corrosion Performance and Environmental Vehicles
The 5083 series itself is a high-magnesium corrosion-resistant aluminum alloy with good corrosion resistance in most environments, but temper differences still affect long-term performance:
- H116 is more stable under long-term seawater immersion or high salt spray, with stronger resistance to lamellar corrosion, commonly used for exterior hull plates, underwater components, or offshore equipment
- H112 performs reliably in general industrial or ventilated environments, suitable for land-based structures or areas without extreme corrosion demands
For structures directly exposed to marine fishing environments, H116 is generally considered more stable and suitable.
Processing and Manufacturing Considerations
During manufacturing, the differences are also evident:
- H112 is easier to bend, form, and deeply process, prioritizing manufacturing process flexibility
- H116, due to higher strength, has relatively limited deformation space and is more suitable for near-final structural applications
This is one reason some manufacturers use H112 extensively in early processing stages.
Application Scope Reference
Common applications of H112
- General structural components
- Parts of transport equipment
- Plates requiring subsequent processing
- Non-critical ship structural areas
Common applications of H116
- Hull structural plates
- Marine engineering equipment
- Load-bearing parts in high-corrosion environments
- Projects requiring marine certification compliance
5083 h116 and h112 selection recommendations
When projects involve long-term marine environments, certification requirements, or corrosion risks, choosing 5083 H116 increases reliability. When the focus is on processing flexibility, cost control, or general structural use, 5083 H112 often offers economic and manufacturing advantages.
