5052 aluminum sheet is a non-heat-treatable 5xxx-series alloy with magnesium as the primary strengthening element. It offers excellent saltwater corrosion resistance, good weldability, and superior formability — making it one of the most widely specified marine-grade sheet products for fuel tanks, boat hulls, chemical enclosures, and general sheet metal work.

5052 aluminum sheet belongs to the 5xxx (Al-Mg) series of non-heat-treatable alloys. Its 2.2–2.8% magnesium content provides strengthening through solid-solution and strain-hardening mechanisms rather than precipitation heat treatment. As a result, 5052 gains its strength from cold working (strain hardening) and is sold in tempers such as O (fully annealed), H32, and H34.
Among commercially available aluminum sheet alloys, 5052 stands out for its resistance to saltwater and marine atmospheres — significantly better than 6xxx-series alloys like 6061, and comparable to 5083 in many coastal-service applications. Its combination of moderate strength, excellent weldability (all standard methods: MIG, TIG, resistance), and good formability makes it a practical choice for boat hulls, fuel tanks, chemical tank skins, road signs, and electronic enclosures.
5052 sheet is governed primarily by ASTM B209 (Aluminum and Aluminum-Alloy Sheet and Plate) and is available in metric and imperial dimensions from global distributors.
Sheet thickness typically ranges from 0.2 mm to 6.0 mm; plate from 6.0 mm upward. Common widths are 1000–1500 mm (standard) or custom widths up to 2600 mm. Lengths are 1000–4000 mm standard, with cut-to-length available. The most frequently ordered tempers for sheet are O (annealed, for maximum formability) and H32 (¼-hard, for balance of strength and bendability).
| Formulaire | Tempérer | Épaisseur (mm) | Largeur (mm) | Longueur (mm) |
|---|---|---|---|---|
| Feuille | O, H32, H34, H36, H38 | 0.2–6.0 | 1000–1500 (up to 2600) | 1000–4000 (cut-to-length) |
| Assiette | O, H32, H34 | 6.0–80 | 1000–2600 | 1000–6000 |
| Bobine | O, H32, H34 | 0.2–3.0 | 1000–1500 | Coil ID 508/610 mm |

Elastic modulus: 69.3 GPa (all tempers). Density: 2.68 g/cm³.
Choosing the right 5052 sheet temper depends on whether your priority is formability (bending, deep drawing) or strength (structural load, fatigue resistance).
| Tempérer | Meilleur pour | Compromis essentiel |
|---|---|---|
| O | Deep drawing, complex bends, maximum formability | Lowest strength; only ~70 MPa yield |
| H32 | Marine hulls, fuel tanks, general sheet — most common spec | Good balance: 175–215 MPa yield with 10–16% elongation |
| H34 | Structural panels, brackets, road signs | Higher yield (~195 MPa) but reduced bendability |
| H36 / H38 | High-strength flat panels where minimal forming is needed | Best strength; limited forming capability |
Practical tip: For most marine and tank applications, H32 is the default choice — it provides enough strength for structural loads while remaining formable for welding-fit joints. If you need to deep-draw a complex shape, start with O temper and specify a post-form strain-hardening requirement.
5052’s standout property is its resistance to saltwater and marine atmospheres. The 2.2–2.8% Mg and 0.15–0.35% Cr content form a stable, adherent oxide film that resists pitting in chloride environments. In salt-spray tests (ASTM B117), 5052 sheet consistently outperforms 6061 and 3003. It is not, however, rated for continuous immersion in strong alkaline solutions.
In O temper, 5052 can be deep-drawn and bent to very small radii — making it suitable for fuel tank shells and boat hull curves. All standard welding methods (MIG, TIG, resistance, gas) work well with 5052. No pre- or post-weld heat treatment is required because the alloy is non-heat-treatable. Weld strength typically approaches the O-temper base-metal value.
At density 2.68 g/cm³, 5052 is lighter than steel by a factor of ~3. H32 yield (175–215 MPa) provides a practical strength-to-weight ratio for marine structural panels without the design complexity of heat-treatable alloys.
5052 sheet is widely used in industries that demand corrosion resistance and moderate strength without heat treatment:
Découpe : CNC plasma, laser, and waterjet all work well on 5052 sheet. For thin gauge (below 1.5 mm), laser cutting produces clean edges with minimal distortion.
Bending: Minimum bend radius depends on temper and thickness. H32 sheet up to 3 mm can typically be bent to 1.5× thickness; thicker gauges or harder tempers require larger radii.
Soudage : 5356 or 5556 filler wire is recommended for 5052 to maintain corrosion resistance in the weld zone. 4043 filler can be used for non-marine applications where strength is prioritized over corrosion match.
Finitions de surface : Mill finish is standard. Anodizing (clear or color) is available for architectural and decorative applications. 5052 anodizes well, producing a uniform oxide layer suitable for outdoor exposure.
Linsy provides a Mill Test Certificate (MTC / 3.1) with every 5052 sheet shipment, documenting chemical composition and mechanical test results per the specified standard (ASTM B209, EN AW-5052, or equivalent). Third-party inspection reports (e.g., SGS test reports) are available on request.
Production is conducted under ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety) certified systems. Standard lead time for stock items is 10–15 days; custom dimensions or special temper requirements may require up to 60 days.

Explore our technical guides for 5052 aluminum:
Q: What is the difference between 5052-H32 and 5052-H34 sheet?
A: H32 is ¼-hard (yield ~175–215 MPa, elongation 10–16%); H34 is ½-hard (yield ~195–240 MPa, elongation 6–12%). H32 is more formable and is the default for marine applications. H34 is chosen when higher flatness stiffness or panel strength is needed.
Q: Can 5052 sheet be anodized?
A: Yes. 5052 anodizes well, producing a uniform oxide layer. Clear and color anodizing are both practical for architectural and decorative finishes.
Q: Is 5052 sheet suitable for fuel tanks?
A: Yes — 5052-O or 5052-H32 is commonly specified for marine fuel tanks and hydraulic reservoirs due to its saltwater corrosion resistance and weldability. Weld filler 5356/5556 maintains corrosion performance in the joint.
Q: What filler wire should I use for welding 5052 sheet?
A: 5356 or 5556 filler is recommended for marine-service welds (matches base-metal corrosion resistance). 4043 filler can be used for non-marine applications where higher weld efficiency is needed.
Q: What is the minimum order quantity?
A: Low MOQs are available for standard-gauge stock items. Contact our sales team for specific quantity thresholds.
Q: How are 5052 sheets packaged for shipping?
A: Sheets are stacked with interleaving paper, strapped to wooden pallets or crated per ASTM B660. Edge protection and corner boards are applied for overseas shipments.
Q: What lead time should I expect?
A: Stock items: 10–15 days. Custom dimensions, non-standard tempers, or large-tonnage orders: up to 60 days.
