Aluminium 5083 H111 plate - Properties, applications & specifications
Properties of aluminium 5083 H111 plate
Aluminium 5083 H111 plate is made from EN AW-5083 (AlMg4.5Mn0.7), a non-heat-treatable aluminium-magnesium alloy widely known as marine grade aluminium for its resistance to seawater and atmospheric corrosion. Euralco supplies this aluminium plate in the O/H111 temper in bulk for project procurement: the standard format 2000 × 6000 mm from stock, longer lengths on request.
In EN 515, H111 means annealed and slightly strain-hardened during subsequent operations such as stretching or levelling. Other tempers, for example 5083 H321, and other thicknesses we supply from production on request, fully in line with the EN specification you ask for. Material certificates per EN 10204 3.1 or 3.2 are available for every delivery.
The strong position of aluminium 5083 H111 plate in shipbuilding comes from its combination of high strength for a non-heat-treatable alloy, excellent weldability and long-term resistance to salt water. Laser cutting and CNC machining to your drawings are available through our network of certified partners; see aluminium machining.

Mechanical properties (EN 485-2)
Aluminium 5083 H111 plate (EN 485-2)
| Thickness (mm) | Rm (MPa) min - max | Rp0.2 (MPa) min | Elongation (%) min |
|---|---|---|---|
| 0.5 - 1.5 | 275 - 350 | 125 | 12 |
| 1.5 - 3.0 | 275 - 350 | 125 | 13 |
| 3.0 - 6.3 | 275 - 350 | 125 | 15 |

Applications by segment
Thanks to its excellent seawater resistance and weldability, aluminium 5083 H111 plate is especially strong in these segments:
Shipbuilding and yacht building
The standard choice for hulls, decks and superstructures of aluminium yachts and boats, thanks to the combination of corrosion resistance and good weldability. Boat builders can also order 5083 H111 as a complete aluminium building kit. More on aluminium in shipbuilding.
Transport
Aluminium 5083 H111 plate suits tank constructions and vehicle components where corrosion resistance and weight saving come together. More on aluminium in transport.
Safety & protection
Robust, corrosion-resistant structures for protection and security applications. More on aluminium for safety & protection.

Global sourcing and supply
At Euralco Europe B.V. we believe that quality, security of supply and competitive pricing are the result of a strong international supply chain. That is why we source our aluminium worldwide through our international production network of carefully selected producers. We always look for the best option for our customers, whether that means material from the Netherlands, elsewhere in Europe or other parts of the world.
Our international production network
Through our international production network we can:
- Extrude profiles in the 6000 and 7000 series (including 6061, 6082, 7010, 7075 and 7175), custom-designed to our customers' requirements.
- Supply plate and coil from production, including special widths and stress-relieved grades for yacht building and shipbuilding.
- Process coils by decoiling, slitting and cutting to length, so we deliver exactly the dimensions our customers need in their production.
- Offer advanced processing through specialised service centres, such as laser-cut kits, machined parts and surface treatments.
By working with both large international producers and specialised niche producers, we combine the advantages of scale with the flexibility of custom production.
Contact us today to find out how Euralco can support your projects with high-quality aluminium plate and extrusions.
Euralco Europe B.V. is a member of the Dutch Aluminium Association (DAA), an industry group run by and for its members, and of Koninklijke Metaalunie, the Dutch association for small and medium-sized manufacturing companies.
