Marine Grade Aluminum Plate: 5083 H111 VS 5083 H321
Last Updated :
5083-H111 and 5083-H321 are both suitable for marine-grade applications, but the specific choice should be determined based on the specific application requirements. H111 focuses more on workability and formability, while H321 emphasizes strength and fatigue life.
5083 aluminum plates are widely used in marine and shipbuilding due to their excellent corrosion resistance and high strength. 5083 marine-grade aluminum plates belong to the 5xxx Al-Mg alloy. It is a typical anti-rust aluminum plate with good corrosion resistance, excellent weldability, and good cold workability.

- Widely Used Tempers: H112, H116, H321, H111
- Applications: 5083 marine-grade aluminum plates are widely used in the production of tanks, automotive fuel tanks, bus bodies, and shipbuilding.
Marine Grade Aluminum Plate 5083 H111
Heat Treatment Condition: H111 temper is lightly strain-hardened. It is essentially in the annealed (O) condition but slightly deformed, enhancing its strength.
Key Characteristics:
- High Corrosion Resistance: It is highly suitable for marine environments due to its excellent seawater corrosion resistance.
- Good Formability: The H111 temper has good ductility and workability, making it suitable for complex forming processes.
- Moderate Strength: Although its strength is lower than that of H321 temper, it still provides adequate strength for marine applications.

Heat Treatment Condition: H321 temper is stabilized by heat treatment, optimizing the aluminum plate's strength after thermal processing while maintaining excellent corrosion resistance.
Key Characteristics:
- Excellent Corrosion Resistance: Like H111 temper, H321 offers excellent corrosion resistance in seawater and other harsh environments.
- Higher Strength: Compared to H111, H321 temper has higher strength, making it suitable for structural components that require higher load-bearing capacity.
- Improved Fatigue Strength: After treatment, H321 temper exhibits higher fatigue resistance under repetitive loads.
Application of Marine Grade Aluminum Plate: 5083-H111 VS 5083-H321
- Marine Grade Aluminum Plate 5083 H111 is most suitable for applications requiring high formability but not necessarily high strength, such as hulls, decks, and other components that require shaping and forming.
- Marine Grade Aluminum Plate 5083 H321 is ideal for components that require high strength and fatigue resistance, such as ship frames, reinforcements, and other load-bearing parts.
Comparison between Marine Grade Aluminum Plate 5083 and 5052
Compared to 5052 aluminum plates, 5083-H321 aluminum plates have excellent corrosion resistance, even in river and marine environments. Therefore, 5083-H321 is widely used in the construction of yacht decks, grain ships, fishing boats, workboats, sand carriers, and components such as engine bases, bulwarks, and shells.

What is the difference between H111 and H321 aluminum?
5083-H111 aluminum and 5083-H321 aluminum are variants of the same material. They have the same alloy composition and many physical properties, but different mechanical properties due to different processing methods.
What is the difference between 5083 H111 and 5083 H112?
5083 H111 refers to aluminum that has undergone slight strain hardening, with moderate strength and good ductility. 5083 H112 is strain-hardened during manufacturing and has similar strength but is suitable for products formed by processes such as rolling or extrusion.
What is 5083 H321?
5083 H321 is a strain-hardened and thermally stabilized aluminum that is stronger and more corrosion-resistant, especially in high-stress environments.
