Good Weldability Al-Mg Alloy 5086 Aluminum Alloy Plate For Marine

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 Company

♦ We have implemented standardized processes to enhance work efficiency, reduce confusion,

minimize errors, and boost overall productivity.

♦ A comfortable and well-lit work environment, combined with a reasonably arranged office layout,

fosters a positive work attitude, healthy interpersonal relationships, and sustained team growth

motivation, while enhancing team cohesion and a sense of belonging.

Our factory own the world advanced equipments, include:

We produced some 5xxx/6xxx series aluminum alloy products for your reference.

5454/5754/5083 alloy oil tank truck/ cylindrical tank trailer

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.

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:

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

Why Choose 5086 for Marine Use?

✔ Balanced cost-performance ratio (cheaper than 5083 but still strong).

✔ Easier to fabricate (better for complex shapes).

✔ Still highly corrosion-resistant (suits most marine environments).
