We supply 5083 Aluminium Marine Plates in marine-service tempers including H116, H321, H111, H112 and O, with material supplied against the required alloy, temper, dimensions and applicable specification.
For marine projects, the distinction between ordinary 5083 plate and material ordered specifically to a marine specification is important. ASTM B928/B928M covers high-magnesium aluminium-alloy sheet and plate intended for marine service and includes Alloy 5083 in H116 and H321 tempers.
5083 Aluminium Marine Plates
Aluminium Alloy 5083 is a 5xxx-series Al-Mg-Mn alloy used extensively for marine structures, including hulls, decks, bulkheads, superstructures and other fabricated vessel components. Its combination of strength, weldability and resistance to seawater exposure makes it one of the principal aluminium alloys used for marine construction.
Marine plate is commonly specified in H116 and H321 when the project calls for a marine-service temper. O, H111 and H112 are also available for applications where their particular strength and forming characteristics are required.
Available supply can include:
- 5083 H116 Aluminium Marine Plates
- 5083 H321 Aluminium Marine Plates
- 5083 H111 Aluminium Marine Plates
- 5083 H112 Aluminium Marine Plates
- 5083 O Aluminium Marine Plates
- ASTM B928/B928M 5083 Marine Plates
- EN AW-5083 Marine Aluminium Plates
- UNS A95083 Marine Aluminium Plates
The exact temper, thickness range and certification should be stated on the purchase requirement.

ASTM B928/B928M is particularly relevant when the purchase order requires aluminium alloy plate for marine service rather than simply generic ASTM B209 plate.
5083 Marine Aluminium Plate Sizes
Plate dimensions vary according to the mill, stock position, thickness and required specification. Published marine-product ranges show H116/H321 material around 3–50 mm thickness, with widths around 1,000–2,600 mm and lengths extending to approximately 12,000 mm for certain supply ranges. Other suppliers publish wider thickness and dimensional ranges, so these figures should be treated as availability references rather than universal limits.
For a commercial enquiry, specify:
- Thickness
- Width
- Length
- Temper
- Quantity
- Applicable standard
- Classification requirement
- Inspection requirement
- MTC requirement
- Cutting requirement
5083 Marine Plate Temper Options
| Temper | Procurement Characteristics | Typical Requirement |
|---|---|---|
| O | Annealed condition with higher formability and lower strength | Formed or heavily bent components |
| H111 | Lightly strain-hardened condition | Marine structures requiring a balance of strength and forming |
| H112 | As-fabricated / controlled mechanical condition | Structural and thicker plate applications |
| H116 | Marine-service temper with specified corrosion-performance requirements | Hulls and marine structures |
| H321 | Marine-service temper with controlled strain-hardening condition | Welded marine structures and structural plate |
H116 and H321 should not simply be treated as interchangeable commercial descriptions. ASTM B928/B928M gives separate mechanical-property requirements for the two tempers and also distinguishes requirements according to thickness.
Mechanical Properties of 5083 Aluminium Marine Plates
The mechanical properties of 5083 marine plate depend on the temper and plate thickness. ASTM B928/B928M provides specific longitudinal requirements for 5083 H116 and H321.

5083 H116 Aluminium Marine Plates
5083 H116 Aluminium Marine Plates are one of the principal material conditions specified for marine aluminium construction. ASTM B928/B928M specifically includes 5083 H116 and subjects this temper to defined mechanical-property and corrosion-resistance requirements.
Published marine product data identifies 5083 H116 plate for applications including hull structures, decks, bulkheads and offshore structures.
For an H116 quotation, the buyer should specify:
5083 H116 + thickness + width + length + ASTM B928/B928M + certification requirement
rather than ordering simply “5083 aluminium plate.”
5083 H321 Aluminium Marine Plates
5083 H321 Aluminium Marine Plates are also covered by ASTM B928/B928M for marine-service applications. The standard provides separate mechanical-property requirements for H321, including thickness-dependent tensile strength and elongation requirements.
Published marine sources identify H321 for welded marine structures, decks, bulkheads and other structural panels.
Where the engineering drawing or vessel specification calls for 5083 H321, the temper should be maintained through procurement and certification rather than substituted with another 5083 temper.
Marine Performance of 5083 Aluminium Plates
5083 is selected for marine fabrication because the alloy combines several properties relevant to vessel construction:
- Aluminium's relatively low density helps reduce structural weight.
- The Al-Mg alloy system provides useful strength without relying on precipitation heat treatment.
- 5083 has established welding applications.
- Its chemistry and product conditions support use in seawater-exposed structures.
- H116 and H321 are specifically addressed for exfoliation and intergranular corrosion resistance under ASTM B928/B928M.
ASTM B928/B928M specifically states that H116 and H321 products covered by the standard are subject to corrosion testing in the as-produced condition.
Applications of 5083 Aluminium Marine Plates
5083 marine plates are supplied for fabrication of:
- Ship hulls
- Hull plating
- Bottom plates
- Side shells
- Deck structures
- Bulkheads
- Superstructures
- Keels and frames
- Yacht structures

- Workboats
- Dredgers
- Offshore structures
- Marine equipment and structural components
Published marine sources identify hulls, decks, bulkheads, superstructures, yachts and offshore structures among the established applications of 5083 marine aluminium.
5083 Aluminium Marine Plate Certification
Marine projects frequently have documentation requirements beyond the basic commercial material certificate. Depending on the vessel specification and classification requirements, enquiries can call for:
- Material Test Certificate
- Chemical composition report
- Tensile test results
- Yield-strength results
- Elongation results
- Dimensional inspection
- Corrosion testing where specified
- Third-party inspection
- Classification-society documentation
- Certificate of origin
- Traceability documentation
