Product Overview

5086 is the preferred hull material for small aluminium boats or larger yachts. Its high strength and good corrosion resistance make it an excellent match for yachting. 5086 has a tendency to undergo stress corrosion cracking and is not used much in aircraft construction as a result.

Our Manufacturing Capabilities
We have implemented standardized processes to enhance work efficiency, reduce confusion, minimize errors, and boost overall productivity.
A comfortable and well-lit work environment fosters positive work attitude, healthy interpersonal relationships, and sustained team growth.

Oversize Sheet Shipping Method
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.
To prevent possible exposure to seawater or rain, we cover the entire cargo with waterproof tarps.
We ensure these sheets are loaded with a low and evenly distributed center of gravity to avoid tilting during transportation.
Key Properties of 5086 Aluminum Alloy
Moderate-to-High Strength

Tensile Strength: 240-300 MPa (depends on temper)
Yield Strength: 110-240 MPa (O temper to H116/H321)

Good fatigue resistance for marine dynamic loads.

Excellent Corrosion Resistance

Resists seawater, salt spray, and marine atmospheres (Mg content: 3.5-4.5%).
Better than 5xxx alloys with lower Mg (e.g., 5052).

Marine Applications of 5086 Aluminum Plate

5086 is widely used in shipbuilding and offshore structures, including:

Hull Construction
Small-to-medium boats (thickness: 3-8 mm)
Superstructures (thickness: 2-6 mm)
Decking & bulkheads (thickness: 4-10 mm)
Offshore & Marine Equipment
Floating docks, gangways, and pontoons (thickness: 5-12 mm)
Fishing vessels & workboats (where cost-efficiency is key)
Comparison with 5083 Aluminum
Property50865083
Mg Content3.5-4.5%4.0-4.9%
StrengthSlightly lower (~10-15%)Higher
Corrosion ResistanceVery good, but slightly less than 5083Best in class
FormabilityBetter for deep drawingSlightly less formable
Why Choose 5086 for Marine Use?
Balanced cost-performance ratio (cheaper than 5083 but still strong)
Easier to fabricate (better for complex shapes)
Highly corrosion-resistant (suits most marine environments)
