Alu Plate 5052 H32 is a widely used aluminum-magnesium alloy plate for industrial fabrication, transportation equipment, marine components, enclosures, and sheet metal processing. It offers a useful balance of strength, corrosion resistance, formability, and weldability. For buyers, choosing the right thickness, plate dimensions, surface quality, and material standard is essential to achieving reliable performance and controlling production costs.
1. What Is Alu Plate 5052 H32?
Alu Plate 5052 H32 is a non-heat-treatable aluminum-magnesium alloy plate. The number 5052 identifies the alloy, while H32 describes its temper. H32 means the material has been strain-hardened and stabilized to achieve a practical combination of strength and formability.
Unlike heat-treatable alloys such as 6061, 5052 gains strength mainly through magnesium alloying and controlled cold working rather than solution heat treatment and artificial aging. It is a common choice for applications that require good atmospheric and marine-atmosphere corrosion resistance, moderate structural strength, and reliable fabrication performance.
5052 H32 aluminum plate is available in different thicknesses, widths, and lengths. Depending on the mill and order requirements, buyers can request standard sheets, cut-to-size plates, protective film, and customized packaging for export shipments.

3. Aluminium 5052 H32 Mechanical Properties
Mechanical properties are important when selecting aluminum plate for load-bearing parts, bent panels, equipment housings, and fabricated components. The H32 temper provides moderate strength while retaining useful formability for many manufacturing processes.
| Property | Typical Reference | Engineering Significance |
| Ultimate tensile strength | Approximately 215–265 MPa | Indicates resistance to tensile failure |
| Yield strength | Thickness- and standard-dependent | Used to evaluate permanent deformation |
| Elongation | Often around 7–12% or higher, depending on gauge and test method | Reflects tensile ductility |
| Elastic modulus | Approximately 70 GPa | Relevant to stiffness and deflection |

Strength and formability
5052 H32 is stronger than commercially pure aluminum grades such as 1050 and 1060. It is also suitable for many bending and forming operations. However, the minimum bend radius depends on plate thickness, rolling direction, tooling, and the required surface finish. For tight bends, confirm the forming requirements before selecting the temper and gauge.
Welding and fabrication
5052 aluminum is commonly fabricated using suitable MIG or TIG welding procedures. Welding heat can reduce the strength associated with cold work near the heat-affected zone. For parts with structural requirements, evaluate the welded joint and design using the applicable engineering rules rather than assuming the original H32 properties remain unchanged throughout the joint.
4. 5052 H32 Chemical Composition
The chemical composition of 5052 aluminum is controlled by the applicable alloy standard. Magnesium is the main alloying element. Small amounts of chromium help improve corrosion performance and control grain structure. The table below gives commonly referenced composition limits; confirm the exact requirements against the standard specified in the purchase order.
| Element | Typical Composition Limit (wt.%) | Role |
| Aluminum (Al) | Remainder | Base metal |
| Magnesium (Mg) | 2.2–2.8 | Main strengthener |
| Chromium (Cr) | 0.15–0.35 | Helps control grain structure and corrosion behavior |
| Manganese (Mn) | Up to 0.10 | Controlled minor element |
| Iron (Fe) | Up to 0.40 | Controlled impurity |
| Silicon (Si) | Up to 0.25 | Controlled impurity |
| Copper (Cu) | Up to 0.10 | Limited to maintain alloy performance |
| Zinc (Zn) | Up to 0.10 | Controlled minor element |
The listed values are general references and should not replace the composition limits in the governing standard. For certified supply, request a mill test certificate showing the actual chemical analysis of the production lot.
5. Aluminum 5052 Density in kg/m³
The density of 5052 aluminum is approximately 2,680 kg/m³, or 2.68 g/cm³. This low density makes aluminum plate much lighter than steel of the same volume. Actual component weight depends on the alloy, dimensions, cutouts, and any coatings or attached parts.
For estimating the weight of a rectangular 5052 H32 aluminum plate, multiply its length, width, thickness, and density. Convert all dimensions to meters before calculating the volume.
Example: A plate measuring 1,000 mm × 2,000 mm × 3 mm has a volume of 0.006 m³. Using a reference density of 2,680 kg/m³, its theoretical weight is approximately 16.08 kg. The actual delivered weight may vary slightly due to dimensional tolerances.
6. 5052 Aluminum Sheet Thickness Chart
5052 H32 aluminum sheet and plate are supplied in a range of gauges for different fabrication needs. The following chart shows common nominal thicknesses and typical uses. It is a selection guide, not a guarantee that every thickness is available in every width and length.
| Thickness | Approx. Gauge Category | Typical Applications |
| 0.5–0.8 mm | Thin sheet | Light covers, panels, and formed parts |
| 1.0–1.5 mm | Light gauge | Enclosures, cabinets, and equipment panels |
| 2.0–3.0 mm | Medium sheet | Fabricated housings, transport components, and brackets |
| 4.0–6.0 mm | Heavy sheet / light plate | Machine covers, supports, and structural fabrications |
| 8.0–12.0 mm | Plate | Equipment components and thicker fabricated parts |
| Over 12 mm | Thick plate | Special industrial applications, subject to mill availability |
When choosing a thickness, consider the required stiffness, load, forming process, corrosion environment, and final component weight. For precision parts, also confirm thickness tolerance, flatness, and surface requirements. If the project uses inch-based dimensions, specify the exact conversion rather than relying only on a gauge number.
7. Main Applications of 5052 H32 Aluminum Plate
The balance of strength, corrosion resistance, and fabrication performance makes 5052 H32 aluminum plate suitable for many industrial and commercial products. The final alloy and temper should always match the load, environment, forming process, and applicable design requirements.
| Industry | Common Products | Material Advantages |
| Transportation | Vehicle panels, covers, and fabricated components | Low weight and good corrosion resistance |
| Marine equipment | Cabin components, covers, and equipment housings | Good performance in marine atmospheres |
| Electrical equipment | Cabinets, control boxes, and enclosures | Fabrication flexibility and moderate strength |

| Sheet metal fabrication | Bent parts, formed panels, and custom components | Suitable for cutting, bending, and welding |
| General construction | Decorative and functional panels | Lightweight and weather-resistant with suitable design |
For continuously immersed seawater service or critical marine structures, do not select an alloy based on corrosion resistance alone. Verify the required alloy, temper, certification, welding procedure, and project standards with the responsible engineer.
8. 5052 H32 Aluminum Equivalent Materials
Buyers may search for a 5052 H32 aluminum equivalent when sourcing from a different country or working with a regional standard. However, an equivalent designation does not automatically guarantee identical chemistry, mechanical properties, tolerances, or certification requirements.
| Reference System | Designation | Important Note |
| AA / North American designation | 5052-H32 | Confirm the applicable product specification |
| European designation | EN AW-5052 / AlMg2.5 | Alloy-family correspondence does not by itself establish temper equivalence |
| Other national standards | Verify by standard and certificate | Check chemistry, mechanical properties, and dimensions |
If your drawing specifies 5052-H32, avoid substituting another alloy or temper based on the alloy number alone. Ask the supplier to provide the relevant standard, mill test certificate, and comparison of required mechanical properties before approving any substitution.
9. Aluminium 5052 Sheet Price and Cost Factors
The price of aluminium 5052 H32 sheet or plate depends on the aluminum market, product dimensions, order quantity, processing requirements, and delivery terms. A reliable quotation should be based on a complete specification rather than the alloy name alone.
Raw aluminum market price
The price of primary aluminum and alloying materials influences the base cost. Market movements, currency exchange rates, and regional supply conditions may change the price between quotation and order confirmation.
