Excellent Corrosion Resistance Al-Mg Alloy Marine Hull 5086 Aluminum Plate
5086 aluminum alloy plate is a marine-grade aluminum material, known for its excellent corrosion
resistance,especially in saltwater environments. With high strength and good weldability, it is widely
used in shipbuilding—particularly for hull structures, decks, and other load-bearing components.

We produced some 5xxx/6xxx series aluminum alloy products for your reference.
For oversize sheet, we use Flat Rack Container for shipping
1) We use suitable securing material, such as wooden blocks, steel straps, and ratchet
tie-downs to firmly fix the aluminum plates to the flat rack.
2) To prevent possible exposure to seawater or rain, we cover the entire cargo with
waterproof tarps.
3) We make sure these sheets are loaded with a low and evenly distributed center of
gravity to avoid tilting during the transportation.
We supply 5086 plates in various tempers (such as H116, H321, and O), with customizable thicknesses
and surface finishes to meet your demands for different projects.
Marine Applications of 5086 Aluminum Plate
5086 is widely used in shipbuilding and offshore structures, including:
1. Hull Construction
Small-to-medium boats (thickness: 3–8 mm).
Superstructures (thickness: 2–6 mm).
Decking & bulkheads (thickness: 4–10 mm).
2. Offshore & Marine Equipment
Floating docks, gangways, and pontoons (thickness: 5–12 mm).
Fishing vessels & workboats (where cost-efficiency is key).
Comparison with 5083 Aluminum
Property | 5086 | 5083 |
Mg Content | 3.5–4.5% | 4.0–4.9% |
Strength | Slightly lower (~10–15%) | Higher |
Corrosion Resistance | Very good, but slightly less than 5083 | Best in class |
Formability | Better for deep drawing | Slightly less formable |
Why Choose 5086 for Marine Use?
✔ Balanced cost-performance ratio
✔ Easier to fabricate
✔ Still highly corrosion-resistant
