5052 Aluminum Alloy for Fishing Boats
This is the sample in our factory display aera.
Alloy: 5052 H32
Manufacture Process: Casting, Hot rolling, Cold rolling, Slitting,Stampong,Welding
Dimension: 4.27x1.87m depth: 1.09m
Weight: 168kg
It has excellent stamping molding performance,good welding performance,high specific strength,
applied to high-speedfishing boats,it not only ensure the beautiful flow of the entireship,but also
ensure the overall strength and rigidity,so that theboat can increase the load Weight and overall
speed during use.It reduces fuel consumption and has a higher recycling value.
The 5052 aluminum plate is a popular choice for small boat construction due to its excellent
corrosion resistance, weldability, and moderate strength, making it ideal for marine environments.
Why Choose 5052 Aluminum?
• Marine-Grade Corrosion Resistance:
Contains 2.5% magnesium and 0.25% chromium, forming a protective oxide layer against
saltwater/freshwater corrosion.
• Lightweight Durability:
1/3 the weight of steel, improving fuel efficiency and payload capacity (ideal for gear-heavy
fishing trips).
• Ease of Fabrication:
Excellent weldability (TIG/MIG) and formability (can be rolled into curved hulls).
Comparison with Other Marine Aluminum Alloys
| Alloy |
Best For |
vs. 5052 |
| 5083 |
Larger boats, high-stress areas |
Stronger but harder to weld |
| 6061 |
Structural frames (not hulls) |
Less corrosion-resistant |
| 3003 |
Non-structural parts (e.g., covers) |
Weaker but cheaper |
→ 5052 is the best balance for small boats where corrosion resistance and formability matter
more than extreme strength.
Real-World Examples
♦ Norway’s Fjord 500: 5052 hull + 5086 deck, weighs only 280 kg (4-person capacity).
♦ China’s "Haiying" Aluminum Boat: 3.2 mm hull, 0.4 m draft (perfect for shallow waters).
