5000 Series Aluminum Alloy 5052 Plate Material For Fishing Boat
5052 is a non-heat-treatable aluminum-magnesium alloy (5xxx series) known for its excellent
corrosion resistance, good formability, and weldability. It's widely used in marine, automotive,
construction, and electronic applications.
5000 Series Aluminum Alloy 5052 Plate Material For Fishing Boat
| Part of the Boat | Common Thickness Range (mm) |
| Hull (bottom and sides) | 3.0 – 6.0 mm |
| Deck and floor | 2.0 – 4.0 mm |
| Internal frames/supports | 2.5 – 5.0 mm |
| Transom, keel reinforcement | 5.0 – 8.0 mm |
Common Tempers
♦ 5052 is primarily used in H32 and H34 tempers (strain-hardened + partially annealed) for
marine.
♦ H32: Moderate strength (tensile strength ~230 MPa), ideal for hull forming due to good formability.
♦ H34: Higher strength (~260 MPa), suitable for load-bearing parts like decks.
Material Selection Tips
• Small recreational boats: Prioritize 5052-H32, 3–4mm thickness.
• Large/commercial boats: Use 5052-H34 for critical areas (e.g., keels) paired with 6061-T6
reinforcements.
• 5052 remains a dominant material for fishing boats, with ongoing advancements targeting
higher performance and smart production technologies.
Comparison with Alternative Alloys
| Alloy | Pros | Cons | Best For |
| 5052 | Corrosion/weld/cost balance | Lower strength than 6xxx/7xxx | High-volume access panels |
| 6061 | Higher strength (T6) | Requires heat treatment | Structural parts (non-door) |
| 3003 | Lower cost, more ductile | Low strength (dents easily) | Interior trim |
| 7075 | Ultra-high strength | Poor corrosion resistance | Racing/military vehicles |
Performance Advantages
Key benefits of 5052 alloy in fishing boats:
✅ Corrosion resistance: Magnesium (2.2–2.8%) and chromium content provide excellent saltwater
resistance, often eliminating the need for coatings.
✅ Lightweight: Density (2.68 g/cm³) is 65% lower than steel, improving fuel efficiency and speed.
✅ Weldability: Compatible with MIG/TIG welding, ensuring strong joints for hull assembly.
✅ Formability: High elongation (≥12% for H32), enabling complex curved hull designs.
