5083 is a 5xxx-series aluminum-magnesium alloy. Its European designation is EN AW-5083 (AlMg4.5Mn0.7). It is one of the strongest aluminum alloys that cannot be heat treated, and it is known mainly for two things: good corrosion resistance and good weldability.

5083 Aluminum Plate Shipment to Singapore
GNEE recently supplied a batch of 5083 aluminum plate to an industrial customer in Singapore. The order was produced in H111 and H112 tempers as requested, checked for chemical composition and mechanical properties, and shipped with Mill Test Certificates (MTC) and export packaging.

Common Uses of 5083 Aluminum Plate
5083 is chosen for parts that see moisture, sea air, or chemicals, and where the part needs to be welded. Common real-world uses:
Boat hulls, decks, and superstructures (new builds and repairs)
Truck and dump truck bodies
Tanker trailers and transport tanks
Water, chemical, and fuel storage tanks
Food and beverage equipment - brewery tanks, dairy tanks, food processing line parts
Low-temperature tanks and vessels (5083 keeps its toughness at low temperature)
General structural fabrication - frames, brackets, platforms, stair treads
Which temper for marine use?
If your plates will be used in seawater - for example a ship hull - we recommend H116 or H321 temper. These are the tempers accepted by classification societies (ABS, DNV, CCS) for marine service. H111 and H112 are fine for general fabrication, but they are not the usual choice for seawater contact parts.
Quality and Documentation
For every order we provide:
Mill Test Certificate (MTC) - actual chemical composition and mechanical test results for your batch
Dimensional and surface check before loading
Optional, if you ask for it:
Third-party inspection (SGS, BV, or other) - available on request
Certificate of origin
Samples are also available. Tell us at the quote stage if you need third-party inspection or a sample, so we can build it into the schedule.
Packaging for Export
Plates are packed for sea or air freight:
Interleaving paper or film between plates to protect the surfaces
Strapped and wrapped on wooden pallets
Corner protection and waterproof wrapping when needed
Packaging can be adjusted to plate size, bundle weight, and how you unload at your port.

FAQ
Is 5083 aluminum plate weldable?
Yes. 5083 welds well. Common filler wires are 5183 and 5356. Welded joints keep most of the base metal strength, which is why 5083 is popular for welded structures.
What is the difference between 5083 and 5086?
5083 has more magnesium (4.0–4.9% vs 3.5–4.5%) and higher strength. 5086 is slightly easier to form. For most marine and structural jobs, 5083 is the stronger choice.
Can you supply small quantities or samples?
Yes. Samples are available. For production orders, minimum order quantity depends on size, thickness, and temper. Send us your requirements and we will confirm.
