5052 h34 aluminum sheet

5052-H34 is an aluminum-magnesium alloy (5XXX series), and H34 indicates a half-hard temper achieved through cold working and stabilization, offering medium strength, corrosion resistance, and good weldability.

5052 H34 aluminum alloy, with its balanced strength, corrosion resistance, and machinability, has become a preferred material in the marine, automotive, and construction industries. Its H34 temper is especially suitable for structures requiring moderate rigidity and corrosion resistance, such as ship hulls, vehicle frames, and building curtain walls.

What is 5052 H34?

• 5052 Alloy: This is an aluminum-magnesium alloy known for its excellent corrosion resistance (especially in marine environments), good weldability, and moderate strength. It cannot be heat-treated but can be strengthened through cold working.
• H34 Temper: The "H" series indicates strain hardening (cold working), and "H34" means the alloy has been strain-hardened and then partially annealed to achieve a half-hard temper. This balances strength and formability.

5052 H34 Aluminum Properties

Excellent Corrosion Resistance

The main alloying element in 5052 is magnesium, which allows a dense and stable oxide film to form on its surface. This film provides strong resistance against various corrosive agents, especially chlorides.

5052 exhibits outstanding corrosion resistance in seawater and marine atmospheric environments, earning it the designation "marine grade aluminum alloy." Its corrosion resistance far surpasses that of hard aluminum alloys like the 2xxx (Al-Cu) and 7xxx (Al-Zn) series, and in some cases even exceeds certain 3xxx series alloys.

Good to Moderate Formability

The 5052 alloy has excellent inherent plasticity, but the H34 temper increases its strength through work hardening, so its formability is slightly lower than the fully annealed O temper. Nevertheless, among medium-strength aluminum alloys, its formability remains very good.

Specific processes:

• Bending: Easy to perform operations like folding and rolling.
• Stamping: Suitable for moderate-depth stamping.
• Deep Drawing: Deep drawing performance is lower than O temper, but still adequate for general deep-drawn parts.
• Note: As an H34 temper, there is a risk of cracking during severe deformation (e.g., small radius bends), so process adjustments may be required depending on the application.

Medium-High Strength

Through work hardening, 5052-H34 achieves significantly higher strength (especially yield strength) than the annealed O temper, while maintaining good toughness. This makes it very suitable for applications requiring moderate structural strength while keeping weight low and corrosion resistance high.

Good Weldability

5052 aluminum alloy can be welded using conventional methods, such as TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding.

Weld joints have high strength and good quality, but it should be noted that the heat-affected zone may soften, resulting in reduced strength.

Cannot Be Strengthened by Heat Treatment

5052 is a non-heat-treatable aluminum alloy. Its strength can only be increased through cold working (work hardening) and cannot achieve the significant strengthening possible in 2xxx, 6xxx, or 7xxx series alloys through solution treatment and aging.

Marine and Offshore Engineering

Due to its seawater corrosion resistance and lightweight properties, 5052 H34 is used in hulls, decks, fuel tanks, and interiors, requiring classification society certification (e.g., DNV, ABS) to ensure long-term reliability.

Automotive Industry

Used in body structural parts, fuel tanks, radiators, interior components, meeting lightweight and corrosion resistance requirements. Roof panels and automotive fuel tanks commonly use 5052 H34 aluminum sheets.

Construction and Decoration

5052 H34 combined with anodizing improves aesthetics and durability, suitable for curtain walls, roofs, window frames, and patterned aluminum sheets.

Excellent salt spray and UV resistance make it ideal for coastal or high-corrosion environments.

Other Fields

Non-critical aerospace structures (e.g., rivets, brackets), electronic device enclosures, hardware products, etc.

5052-H34 Performance

• Strength: Higher tensile strength compared to other common tempers, such as H32
• Corrosion Resistance: Excellent, especially suitable for marine environments
• Fatigue Strength: High fatigue limit
• Formability: Good, but slightly lower than H32 due to higher degree of work hardening
• Weldability: Good

5052 H34 Aluminum Machining and Welding

Machining Processes

• Cold Working: Can be formed by cold rolling, stamping, bending, etc., but the H34 temper is suitable for simple shapes. For complex bends, H32 is recommended.
• Annealing: Annealing temperature 345°C, used to relieve stress or restore plasticity.
• Short-Process Production: New patented process can skip intermediate annealing, reducing costs, suitable for products with thickness ≥0.8mm.

Welding Performance

• Recommended to use ER5356 filler wire (Mg 4.5-5.6%), weld strength approaches base metal, with good corrosion resistance.
• Post-weld stress relief is recommended to avoid intergranular corrosion.

Advantages and Limitations of 5052 H34 Aluminum

Advantages of 5052 H34 Aluminum

• Corrosion Resistance: Magnesium forms a dense oxide film, providing outstanding resistance to seawater, salt spray, and industrial environments.
• Weldability: Easy for arc and resistance welding, suitable for structural connections.
• Cost-Effectiveness: More economical than high-strength alloys like 5083, suitable for non-critical load-bearing components.

Limitations of 5052 H34 Aluminum

• Strength Limit: Medium strength, not suitable for high-load structures (e.g., bridges, pressure vessels).
• Machinability: Poor cutting performance in annealed state; H34 temper requires optimized tooling parameters.

5052 H34 Aluminum Comparison and Selection

• 5052 H34 vs H32: H34 has higher strength but lower ductility, suitable for parts requiring higher rigidity (e.g., ship frames); H32 is easier to form, suitable for complex bends (e.g., automotive fuel tanks).
• 5052 H34 vs 5083 H116: 5083 has higher magnesium content, superior strength and corrosion resistance, but higher cost, suitable for high-corrosion environments (e.g., deep-sea equipment).

What is the difference between 5052 H32 and H34?

Compared to 5052-H32, 5052-H34 has higher strength and hardness but reduced formability. The choice between the two will depend on the specific requirements of the application, including the balance of strength and formability needed.
