If you are manufacturing marine vessels, automotive fuel tanks, or refrigerated trailers, choosing the right aluminum alloy is the most important decision you will make. You need a material that does not rust in harsh environments, bends easily without cracking, and holds strong after welding.
5052 aluminum sheet is one of the most stable and mature industrial aluminum alloys available. Known as "Marine Grade Aluminum," it belongs to the 5xxx series (Al-Mg alloys) and is strengthened by cold working rather than heat treatment.
GNEE is a leading marine-grade aluminum supplier. Contact us today for a quick quote and a free material testing report!
Why Choose 5052 Aluminum?
- Non-heat-treatable: Strengthened through cold working (e.g., H32, H34, and H38 tempers).
- High Magnesium Content (2.2%–2.8%): Provides excellent natural rust and saltwater resistance.
- Excellent Formability: Highly suitable for deep drawing, stamping, and tight bending.
- High Welding Strength: Retains approximately 95% of its base strength after welding.
Chemical Composition of 5052 Aluminum plate
The chemical makeup of an alloy determines how it acts in the real world. Here is the standard chemical composition of 5052 aluminum.
| Element | Content (wt%) |
| Magnesium (Mg) | 2.2 – 2.8 |
| Chromium (Cr) | 0.15 – 0.35 |
| Silicon (Si) | ≤0.25 |
| Copper (Cu) | ≤0.10 |
| Iron (Fe) | ≤0.40 |
| Manganese (Mn) | ≤0.10 |
| Aluminum (Al) | Remainder |
Mechanical Properties of 5052 Aluminum plate
Different tempers offer different balances of strength and flexibility. Below are the mechanical properties for standard tempers like O (fully soft), H32 (quarter-hard), H34 (half-hard), and H38 (full-hard).
| Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|
5052 O (Soft) |
190 | 89 | 25 |
| 5052 H32 | 228 | 193 | 12–18 |
| 5052 H34 | 260 | 214 | 10–12 |
| 5052 H38 | 295 | 255 | 7 |
Key Physical Metrics:
Density: 2.68–2.72 g/cm³ (Lightweight, saving fuel in transport applications).
Hardness: ≈60 HB.
Fatigue Strength: 120 MPa (Highly resistant to constant vibration, perfect for vehicle bodies).
Thermal Conductivity: 138 W/m·K.
Corrosion Resistance of 5052 Aluminum plate
| Environment | Corrosion Rate / Depth |
| Seawater Immersion | 0.05 mm / year |
| Salt Spray Test | >1000 hours (No pitting) |
| Tidal Zones | Very light uniform corrosion |
| Dry Inland (20 Years) | <0.01 mm |
| Industrial (20 Years) | 0.02 mm |
| Coastal Humid (20 Years) | 0.05 mm |
Conclusion: Whether it is a boat hull sitting in saltwater or an outdoor chemical tank, 5052 will maintain its structural integrity for decades.
Processing and Welding Performance
5052 excels on the production floor, which keeps your scrap rates low and yield rates high.
Bending: Excellent. It can handle small bending radii without cracking on the edges.
Stamping/Drawing: Very good. It has a high drawing ratio of 2.0–2.5.
Welding: Outstanding.
Welding Strength Data:
When you weld aluminum, the heat usually weakens the metal. For 5052, the base material has a tensile strength of 228 MPa. The weld seam retains a strength of 217 MPa. That is a 95% strength retention rate. Your welded joints remain incredibly secure.
