5454 H32 aluminum plate sheet

5454-H32 aluminum alloy is a specific temper of 5454 aluminum alloy obtained through strain hardening and stabilization treatment. Compared with the fully annealed condition (O temper) and the fully hardened condition (H38 temper), the strength of 5454-H32 aluminum alloy is about one-fourth of the strength of these two states.

5454-H32 aluminum alloy is widely used in fields requiring excellent strength and corrosion resistance, such as marine and offshore structures, as well as areas needing high strength and good formability.

5454 H32 aluminum is a typical Al-Mg anti-rust aluminum alloy, achieving medium strength and excellent corrosion resistance through cold working and stabilization annealing processes (H32 temper). It is widely used in areas with high requirements for weight, corrosion resistance, and welding performance.

5454 aluminum alloy belongs to medium-to-high strength non-heat-treatable alloys. Its main features are:

• Main alloying elements: Magnesium (Mg) and Manganese (Mn).
• Magnesium (Mg): Mainly provides solid solution strengthening, improves strength, while maintaining good corrosion resistance.
• Manganese (Mn): Assists in enhancing strength and improves the alloy's recrystallization temperature.

What does H32 aluminum mean?

In aluminum alloys, "H32" denotes the temper or state of the material. Specifically, H32 indicates a strain-hardened and stabilized condition. It means:

Strain Hardened (H): Aluminum alloys tempered to an H state are strengthened through a process known as strain hardening or cold working, involving plastic deformation such as rolling or stretching, which changes its crystal structure and increases its strength. The temper is denoted by the letter H followed by a number (e.g., H32, H34, H36), with each number representing a different level of strain hardening.

Stabilized (32): The number following H indicates a specific stabilization treatment applied to the alloy after strain hardening. For H32, the alloy is stabilized to approximately one-fourth the strength of fully annealed (O temper) aluminum, but compared to fully hardened states like H38, it offers significantly better formability and corrosion resistance.

H32 aluminum is an aluminum alloy that has been strain-hardened to a quarter-hard state and then stabilized to achieve a balance of strength, formability, and corrosion resistance, suitable for various applications including marine structures, automotive components, and architectural uses.

Comparison of 5454 H32 Aluminum with Other Common Aluminum Alloys

• 5454 H32 vs. 5052 H32: 5454 H32 has higher strength, especially at elevated temperatures. If the strength of 5052 is insufficient but using the more expensive 5083 is not required, 5454 is a good upgrade choice.
• 5454 H32 vs. 5083 H32: 5083 has higher strength and is among the highest-strength Al-Mg alloys, commonly used in applications requiring extremely high strength, such as warships and large hulls. 5454 has slightly lower strength but better formability and potentially lower cost.
• 5454 H32 vs. 6061 T6: 6061 is a heat-treatable alloy with strength usually higher than 5454 H32, but its corrosion resistance (especially after welding) and formability are inferior to 5454. The choice depends on whether the primary requirement is strength or corrosion resistance/weldability.

Precautions for 5454 H32 Aluminum

• Stress corrosion cracking: High-stress conditions in high-temperature chloride-containing environments should be avoided. Stress-relief annealing or using H34 temper (higher cold work) can improve resistance.
• Surface treatment: Anodizing 5454 H32 aluminum can further enhance corrosion resistance and decorative appearance, suitable for architectural and automotive decorative components.
• Storage and transportation: Avoid direct contact with metals such as copper or steel to prevent galvanic corrosion; store in a dry environment to protect the surface oxide layer.

With its excellent corrosion resistance, medium strength, and good weldability, 5454 H32 aluminum has become a preferred material in marine engineering, automotive lightweighting, and chemical equipment fields. By reasonably designing process parameters (such as cold work amount and annealing temperature) and strictly controlling welding quality, its comprehensive performance advantages can be fully utilized to meet diverse engineering requirements.

5454 H32 is a well-balanced medium-to-high strength Al-Mg alloy, renowned for its outstanding corrosion resistance (especially stress corrosion resistance), good weldability, and ability to maintain strength at elevated temperatures.

What is the difference between 5052 H32 and H34?

The main difference between the H32 and H34 states of 5052 aluminum alloy lies in their degree of strain hardening and corresponding mechanical properties. The selection between these two states in engineering applications needs to consider the material's strength, hardness, and formability.

Strength and Hardness

H34 state exhibits a higher degree of strain hardening compared to H32. This means that after cold working, aluminum alloys in the H34 state typically have higher strength and hardness. Therefore, when applications require higher strength materials, the H34 state may be more suitable.

Formability

In contrast, H32 state has a lower degree of strain hardening. This allows 5052 aluminum alloy in H32 state to have better formability and ductility in certain forming operations. Thus, for applications requiring better formability, such as complex forming or deep drawing operations, H32 state might be more appropriate.

The choice between H32 and H34 states of 5052 aluminum alloy depends on specific application requirements. If higher strength and hardness are needed, H34 state is preferable; whereas if excellent formability is required, H32 state may be more suitable. In practical engineering, factors such as mechanical properties, processing techniques, and cost should be comprehensively considered to make the optimal choice.
