Aluminium 5052 H32 is a widely used aluminum-magnesium alloy known for its excellent corrosion resistance, good formability, reliable weldability, and moderate strength. It is a popular choice for aluminum sheet metal fabrication, marine components, transportation equipment, industrial enclosures, and general engineering applications. Compared with many other aluminum alloys, 5052 H32 offers a practical balance of strength, durability, and ease of processing.
For buyers, engineers, and manufacturers, understanding aluminium 5052 H32 properties is essential when selecting the right sheet thickness, mechanical performance, and surface finish. This guide covers its chemical composition, density, yield strength, hardness, equivalent grades, price factors, and common applications. It also answers important questions about the meaning of H32, its strength compared with 6061-T6, marine suitability, and welding performance.


Aluminium 5052 H32 is a non-heat-treatable aluminum alloy in the 5000 series. Magnesium is its main alloying element, while chromium helps improve corrosion resistance and other material characteristics. Its strength comes primarily from solid-solution strengthening and controlled cold working rather than heat treatment.
The alloy is commonly supplied as aluminum sheet, plate, and coil. The H32 temper indicates that the material has been strain hardened and stabilized to achieve a balance of strength and formability. It is suitable for bending, cutting, stamping, and welding when the processing conditions are properly selected.
Typical applications include marine equipment, fuel tanks, vehicle components, electrical cabinets, architectural panels, pressure-related equipment, and industrial sheet metal parts. The exact grade and temper should always match the mechanical requirements and applicable product standard.
The following table summarizes commonly referenced properties of aluminium 5052 H32. Mechanical values can vary with product thickness, testing conditions, and the governing specification. Use the values in the applicable standard and mill test certificate for engineering calculations.
| Property | Typical Reference Value | Unit |
| Alloy | 5052 | Aluminum alloy |
| Temper | H32 | Strain hardened and stabilized |
| Density | 2.68 | g/cm³ |
| Tensile strength | Approximately 228 | MPa, typical reference |
| Yield strength | Approximately 193 | MPa, typical reference |
| Brinell hardness | Approximately 60 | HB, typical reference |
| Elastic modulus | Approximately 70.3 | GPa |
| Thermal conductivity | Approximately 138 | W/(m·K) |
| Heat treatment | Not heat-treatable for strengthening | Processing characteristic |
These figures are reference values, not guaranteed minimums for every thickness. When ordering aluminium 5052 H32, confirm the required tensile strength, yield strength, elongation, dimensional tolerances, and product standard with your supplier.
The chemical composition of 5052 aluminum determines its corrosion resistance, strength, and fabrication performance. Magnesium is the primary alloying element. Chromium supports corrosion resistance and helps control the alloy's microstructure.
| Element | Typical Specification Limit (wt.%) | Function |
| Magnesium (Mg) | 2.2–2.8 | Main alloying element; contributes to strength and corrosion resistance |
| Chromium (Cr) | 0.15–0.35 | Supports corrosion resistance and microstructure control |
| Iron (Fe) | ≤0.40 | Controlled impurity |
| Silicon (Si) | ≤0.25 | Controlled impurity |
| Copper (Cu) | ≤0.10 | Limited to maintain corrosion performance |
| Manganese (Mn) | ≤0.10 | Minor alloy constituent |
| Zinc (Zn) | ≤0.10 | Controlled impurity |
| Aluminum (Al) | Remainder | Base metal |
The values above are common reference limits. Other elements and total impurity limits are also controlled by the applicable specification. Always refer to the agreed standard and the mill test certificate for the actual chemical analysis of a production batch.
Yield strength is the stress at which a material begins to deform permanently. Tensile strength is the maximum stress recorded during a tensile test. Both are important when engineers evaluate aluminium 5052 H32 for load-bearing parts, formed panels, and equipment housings.
A commonly cited reference value for 5052 H32 yield strength is approximately 193 MPa, with tensile strength around 228 MPa. Actual minimum values depend on thickness and the applicable standard. Design calculations should not rely on typical values alone.
The alloy also offers good fatigue performance, especially in fabricated parts subject to repeated loading. However, fatigue life depends on stress level, surface condition, component geometry, and weld details. For safety-critical applications, use validated design data and test results rather than general reference figures.
The typical Brinell hardness of aluminium 5052 H32 is approximately 60 HB. Hardness provides a useful indication of resistance to indentation, but it does not replace tensile, yield, or fatigue testing when evaluating material performance.
H32 material combines moderate strength with useful cold-forming capability. It can be bent, roll formed, punched, and fabricated into many sheet metal products. The minimum bending radius depends on thickness, bend direction, tooling, and the required surface quality. A forming trial is recommended for tight bends or complex components.
For applications that require extensive deep drawing or maximum softness, 5052-O may be more suitable. For applications that need higher strength, other tempers or alloys may be considered after evaluating forming and corrosion requirements.
The density of aluminium 5052 H32 is approximately 2.68 g/cm³, or 2,680 kg/m³. This low density makes it useful where reducing component weight is important, including transport equipment, marine structures, enclosures, and fabricated sheet metal products.
For a flat sheet, the estimated mass can be calculated using the following formula:
Weight (kg) = Length (m) × Width (m) × Thickness (mm) × 2.68
For example, a 2,000 mm × 1,000 mm × 2 mm sheet has an approximate mass of 10.72 kg. This is a theoretical estimate; actual delivery weight may vary slightly because of dimensional tolerances and processing.
Aluminium 5052 H32 sheet is available in different thicknesses, widths, lengths, and surface finishes. The following are common ordering dimensions for reference. Actual availability depends on mill capability, stock, and order quantity.
| Thickness | Common Widths | Supply Form | Typical Applications |
| 0.5–1.0 mm | 1000–1500 mm | Sheet or coil | Covers, panels, lightweight enclosures |
| 1.2–2.0 mm | 1000–1500 mm | Sheet or coil | Cabinets, vehicle parts, formed components |
| 2.5–3.0 mm | 1000–2000 mm | Sheet | Marine components, equipment panels |
| 4.0–6.0 mm | 1000–2000 mm | Plate or sheet, subject to availability | Structural fabrications and heavy-duty components |
These ranges are illustrative rather than a guaranteed stock list. Buyers should confirm the exact thickness tolerance, flatness, width, length, edge condition, surface protection, and inspection requirements before placing an order.
A 4x8 aluminum sheet usually measures 4 ft × 8 ft, or approximately 1219 mm × 2438 mm. It is a common format for North American fabrication, equipment panels, vehicle parts, and general sheet metal work.
When purchasing 5052 H32 aluminum sheet 4x8, specify the thickness, required quantity, surface condition, and cutting requirements. Confirm whether the supplier offers the exact dimensions as standard stock or needs to cut the sheet to size.
The combination of corrosion resistance, formability, weldability, and moderate strength makes 5052 H32 suitable for a wide range of industrial applications.
For components in direct seawater contact, pressure service, or other safety-critical applications, material selection must consider the complete design, applicable regulations, weld details, and certification requirements. The 5052 designation alone does not establish suitability for every marine or pressure application.
Aluminium 5052 H32 may be identified by related designations such as AA 5052-H32, UNS A95052, and AlMg2.5 in relevant material references. These names help buyers identify the alloy across different documentation systems, but they do not automatically mean that every product specification is interchangeable.
When comparing an equivalent grade, check the chemical composition, temper, mechanical property requirements, dimensions, applicable product standard, and certification documents. A nominally similar alloy may have different minimum strengths, corrosion requirements, or manufacturing tolerances.
For export orders, it is best to state the full designation as 5052-H32 and specify the standard required by the buyer. This reduces the risk of receiving material that has the correct alloy number but the wrong temper or documentation.
The price of aluminium 5052 H32 depends on the aluminum market, alloy and temper, sheet thickness, dimensions, order quantity, surface requirements, processing costs, and delivery terms. A single price per kilogram cannot accurately represent every order.
Thin sheets and custom-cut sizes may have different processing costs from standard dimensions. Small orders can also have a higher unit price than larger production orders because of setup, cutting, packaging, and handling costs.
For an accurate aluminium 5052 H32 price per kg, buyers should provide the alloy and temper, thickness, width, length, quantity, destination port, and required surface finish. It is also important to clarify whether the quotation is based on EXW, FOB, CIF, or another trade term.
When comparing supplier quotations, check the material specification, dimensional tolerances, packaging, inspection documents, and delivery schedule alongside the quoted price. A lower price may not represent better value if the material or documentation does not meet the project requirements.
The designation has two parts: 5052 identifies the aluminum alloy, while H32 identifies its temper. The 5052 alloy belongs to the aluminum-magnesium series and is valued for corrosion resistance and good fabrication performance.
The H temper indicates strain-hardened material. In H32, the first digit 3 identifies strain hardening followed by stabilization, and the final digit 2 indicates a quarter-hard condition within this temper system. Stabilization helps achieve a more stable combination of mechanical properties.
Therefore, aluminium 5052 H32 is a magnesium-containing aluminum alloy that has been strain hardened and stabilized. This condition provides a useful balance of strength, corrosion resistance, and formability for many sheet metal applications.
In general, 6061-T6 has higher yield strength than 5052-H32. The two alloys use different strengthening methods: 5052-H32 is strengthened mainly by cold working, while 6061-T6 is strengthened through solution heat treatment and artificial aging.
| Comparison | 5052-H32 | 6061-T6 |
| Strength | Moderate | Generally higher |
| Corrosion resistance | Very good, including many marine atmospheres | Good for many general environments |
| Formability | Good for many sheet metal operations | More limited in the T6 temper |
| Typical selection | Marine sheet metal and formed components | Structural parts and machined components |
Choose 5052-H32 when corrosion resistance, sheet forming, and welding are important. Consider 6061-T6 when higher strength and machinability are key requirements. The final choice should account for the component design, service environment, fabrication process, and properties after welding.
5052-H32 is often used in marine environments because it offers very good resistance to corrosion in salt-laden atmospheres and can be readily fabricated into many marine components. Typical uses include cabinets, covers, interior panels, and selected equipment parts.
However, the term marine grade does not mean that every 5052-H32 product is automatically approved for every shipbuilding application. Primary hull structures, continuously immersed components, and classification-controlled projects may require a different alloy, temper, product standard, or third-party certification.
Before ordering aluminum for a vessel or offshore project, confirm the operating environment, design requirements, applicable classification society rules, and material certification requirements. Where certified marine plate is specified, follow the project specification rather than substituting 5052-H32 based only on its corrosion resistance.
Yes. Aluminium 5052 H32 has good weldability and is commonly joined using suitable gas metal arc welding (MIG/GMAW) and gas tungsten arc welding (TIG/GTAW) processes. Correct filler metal selection and welding preparation help produce reliable joints.
For many 5xxx-series aluminum applications, filler alloys such as 5356 may be considered. The correct choice depends on the service environment, joint design, required strength, corrosion requirements, and applicable welding procedure. Consult a qualified welding engineer for critical assemblies.
As with other strain-hardened aluminum alloys, welding heat can reduce the strength of the heat-affected zone. Clean the joint surfaces, remove oxide and contamination, use suitable shielding gas, and control heat input. For structural or pressure-related components, use a qualified welding procedure and verify the properties required by the design.
Choosing the right supplier is important for maintaining consistent quality, dimensional accuracy, and reliable delivery. Buyers should confirm the supplier's ability to provide the required alloy, temper, dimensions, surface quality, and documentation before placing an order.
A complete inquiry helps the supplier quote accurately and reduces the risk of delays caused by missing specifications. For repeat orders, keeping the approved material specification and inspection requirements consistent also helps maintain quality from batch to batch.
The commonly referenced density of aluminium 5052 H32 is approximately 2.68 g/cm³. This value can be used for preliminary weight estimates, while actual dimensions and tolerances should be used for final calculations.
A commonly cited typical yield strength is approximately 193 MPa. The specified minimum can vary with product thickness and standard, so buyers should verify the applicable material specification and mill test certificate.
Yes. It offers good formability for many sheet metal applications. The achievable bend radius depends on thickness, bend direction, tooling, and the required surface finish. Test the forming process when tight bends or complex shapes are required.
Provide the alloy, temper, thickness, width, length, quantity, surface requirements, destination, and trade terms. These details allow the supplier to calculate a quotation based on the actual order rather than a general market estimate.
Aluminium 5052 H32 is a versatile choice for buyers who need good corrosion resistance, moderate strength, weldability, and reliable sheet metal forming performance. Selecting the right thickness and confirming the required mechanical properties can help improve product quality and control material costs.
