5052 h32 aluminum sheet

5052 is an aluminum-magnesium alloy that belongs to the rust-resistant aluminum category. It cannot be strengthened by heat treatment, but its strength can be improved through cold working. The H32 temper designation indicates that the material has undergone strain hardening followed by stabilization treatment, giving it higher strength than the O temper (annealed state) while maintaining good formability.

5052 H32 aluminum sheet (with a thickness of less than 6mm) is a typical aluminum-magnesium (Al-Mg series) alloy material. It achieves the H32 condition through partial annealing, strain hardening, and stabilization treatment. It combines medium strength, excellent corrosion resistance, and good formability, making it widely used in applications requiring lightweight and weather resistance.

What is 5052 H32 aluminum?

5052 H32 aluminum is an aluminum alloy that has undergone strain hardening and stabilization treatment. Its strength is about a quarter of the range between the annealed state (O) and the full hard state (H38), providing good mechanical performance and durability.

• Alloy class: 5052 (an aluminium-magnesium alloy)
• Temper (H32): Strain hardened and stabilized (¼ hard) — gives moderate strength and good formability.

5052 h32 aluminum sheet thickness tolerance

The thickness tolerance for 5052 H32 aluminum sheet depends on the sheet thickness range and manufacturing standard (e.g., ASTM B209). Below is a general reference based on ASTM B209 / EN 485-3 tolerances for aluminum alloy sheets and plates.

Typical Thickness Tolerances for 5052-H32 Aluminum Sheet

Notes

Based on ASTM B209 for rolled aluminum sheet and plate.

Actual tolerance can vary slightly by manufacturer or mill.

H32 temper (strain hardened and stabilized) does not change dimensional tolerance, only mechanical properties.

For precision applications, request mill-certified tolerance sheets from the supplier.

5052 h32 aluminum properties

• Corrosion Resistance: 5052 H32 aluminum has excellent corrosion resistance, remaining stable in marine environments and other highly corrosive conditions.
• Strength: Higher strength than the annealed state (O), but not as hard as the fully hard temper (H38).
• Formability: Good, suitable for various forming processes such as stamping and bending.
• Weldability: Good, can be joined using common welding methods such as TIG and MIG.
• Ductility: Good, allowing it to maintain shape and withstand deformation in various applications.
• Machinability Rating: Moderate. Although aluminum alloys are generally easy to machine, specific performance may vary depending on machining techniques and equipment.
• Good fatigue strength under repeated stress conditions.

5052 h32 aluminum corrosion resistance and surface treatment

5052 h32 Aluminum Corrosion Resistance

The natural corrosion resistance of 5052 aluminum comes from magnesium, which forms a dense oxide film. Its salt spray corrosion resistance is superior to 3-series and 6-series aluminum alloys. In salt spray tests, no pitting occurs after 240 hours, making it suitable for marine environments or outdoor equipment.

5052 h32 Aluminum Surface Treatment Options

• Anodizing: Can form a 10-25μm oxide film, increasing salt spray resistance to over 500 hours. The color is mainly gray-white and can be electrolytically colored (e.g., black).
• Fluorocarbon Coating: PVDF coating has a weather resistance of up to 20 years, suitable for curtain walls or outdoor cabinets.
• Pretreatment Requirements: Thorough degreasing (alkaline wash or solvent cleaning) + acid etching (to remove rolling oxide scale) is required to ensure uniform coating.

• Bending Performance: 5052 aluminum sheet in H32 temper has good bending performance, allowing 90° bends without cracking. The minimum bend radius varies depending on sheet thickness and temper; for example, the O temper bend radius can reach 0.5 times the sheet thickness, while H32 may require up to 1.2 times the sheet thickness. In practice, refer to specific technical standards or confirm with the supplier.
• Welding Performance: 5052 H32 aluminum sheet has good weldability and can be welded using Gas Tungsten Arc Welding (GTAW) or Gas Metal Arc Welding (GMAW), with high weld strength retention.
• Surface Treatment: 5052 aluminum is suitable for anodizing, which can improve corrosion resistance and surface hardness.

5052 h32 applications

• Electronics: Instrument housings, computer cases, cabinets, etc.
• Transportation: Automotive fuel tanks, bus luggage racks, ship sheet metal parts, etc.
• Architectural Decoration: Curtain wall panels, etc.

5052 h32 vs h34

Compared to 5052-H32, 5052-H34 has higher strength and hardness, but lower ductility. The choice between the two will depend on the specific requirements of the application, including the need for strength versus formability.

What is the difference between 5052 H32 and 5052 H36?

Compared to 5052-H32, 5052-H36 has higher strength and hardness, but reduced ductility. The choice between the two depends on the specific requirements of the application, including the need for strength versus formability.

What is the difference between 5052 H32 and 5052 O?

5052 H32 Aluminum vs. 5052 O Aluminum

5052 H32 achieves a balance of strength and formability, suitable for applications requiring medium strength and good corrosion resistance. In contrast, 5052-O is softer and more ductile, making it ideal for applications where ease of forming and high ductility are more important than strength.

5052 h32 purchasing and storage recommendations

• Temper Selection: Focus on H32 temper, which indicates the material has undergone strain hardening and stabilization treatment, with higher strength than the annealed state (O temper) while maintaining good formability, suitable for bending operations.
• Specification Confirmation: Specify the required thickness, width, and length. Suppliers usually provide standard sizes and can also customize on demand.
• Surface Quality: The sheet surface should be free of cracks, corrosion spots, and salt marks. Minor peeling or bubbles within allowable limits are acceptable.
• Protective Storage: Although 5052 H32 aluminum is corrosion-resistant, it is recommended to store it in a dry and ventilated warehouse, avoiding contact with corrosive substances such as acids or alkalis.

What is the difference between 6061-T6 and 5052 H32?

• 5052-H32 is preferred for parts that require bending, forming, or corrosion resistance.
• 6061-T6 is chosen for high-strength, structural, or machined components.

Is 5052 H32 aluminum bendable?

Yes.

5052-H32 aluminum has excellent formability and bendability due to its magnesium content and moderate hardness.

It can be bent, rolled, or stamped without cracking, especially in thinner gauges.

It’s commonly used in sheet metal fabrication, vehicle panels, and marine structures where smooth bends are required.
