5086 h32 aluminum plate sheet

5086 H32 aluminum alloy belongs to the Al-Mg (5xxx series) corrosion-resistant aluminum, known for its excellent corrosion resistance, good weldability, and medium strength. It is widely used in marine, defense, and transportation applications. H32 is a common temper that indicates the material has been strain-hardened and stabilized to achieve medium strength.

5086 is particularly suitable for welded structures exposed to marine or corrosive industrial environments. When higher exfoliation corrosion resistance is required, 5086-H116/H321 should be considered. When strength is the top priority and the working environment is less corrosive, or when a large amount of machining is needed, 6061-T6 may be a better choice.

What does 5086 H32 aluminum mean?

5086: Alloy designation, indicating aluminum-magnesium alloy.

H32: Temper designation, indicating the alloy has undergone strain hardening through cold working, followed by stabilization treatment, resulting in medium strength and good formability.

The "H temper" represents the state of aluminum alloys that have been "strain hardened (cold worked) + stabilized, " suitable for 5000 series alloys that cannot be strengthened by heat treatment (such as quenching and aging). These alloys are "non-heat-treatable, " and their strength mainly depends on cold working. The detailed meaning of H32 is as follows:

• H: Strain-hardened condition;
• 3: Stabilization treatment after strain hardening (relieves internal stress from cold working, prevents later deformation, stabilizes mechanical properties);
• 2: Moderate strain hardening level (tensile strength corresponds to the medium level of cold worked states of this alloy).

5086 H32 Aluminum Advantages

Excellent Corrosion Resistance

Especially suitable for seawater, freshwater, industrial atmospheres, and other corrosive environments; it is a typical marine-grade aluminum.

Medium Strength, Higher Than Common 5052 Aluminum Alloy

Stronger than 5052 but slightly lower than 5083, and more suitable for long-term marine environments than 6061.

Outstanding Weldability

Suitable for MIG and TIG welding. After welding, the strength reduction is small, making it one of the preferred materials in the shipbuilding industry.

Good Fatigue Resistance and High Toughness

Maintains stable performance at low temperatures without becoming brittle; ideal for refrigeration equipment and low-temperature containers.

Good Formability

Can be manufactured into plates, coils, tubes, and rods; suitable for rolling, bending, and forming.

5086 H32 Aluminum – Excellent Corrosion Resistance

5086 H32 is one of the aluminum alloys with the best corrosion resistance, especially suitable for harsh environments:

• Marine corrosion resistance: The magnesium oxide film formed is dense and resists seawater and salt spray corrosion, far superior to 1000 series pure aluminum and 2000 series aluminum alloys.
• Atmospheric corrosion resistance: In industrial and rural atmospheres, it shows almost no rusting and can be used long-term without additional coatings.
• No stress corrosion cracking (SCC): 5000 series alloys do not contain copper, avoiding the stress corrosion cracking issues found in 2000 series and 7000 series alloys.

5086 h32 aluminum properties

• Marine grade: With excellent corrosion resistance, specifically designed for use in harsh marine environments.
• High strength: Higher strength compared to other common alloys such as 5052.
• Non-heat treatable: Belongs to the 5xxx series (aluminum-magnesium alloys), strengthened by strain hardening (cold working) instead of heat treatment.
• Excellent corrosion resistance: Provides superior corrosion resistance, especially in marine environments like seawater, and also performs well in industrial atmospheres.
• Excellent weldability: Easily welded using TIG and MIG methods, retaining most of its mechanical strength in the weld zone.
• Good formability: Can be processed into complex shapes, but its ductility in the H32 temper is lower than in the annealed condition.
• Non-magnetic: It is non-magnetic.

5086 H32 Aluminum Plate and Sheet Fabrication & Processing

• Heat treatment: H32 temper indicates that the aluminum has undergone specific heat treatment processes to achieve strain hardening and stabilization.
• Machinability: It is easy to machine, weld, and form. However, due to its high magnesium content, special considerations may be required for welding.
• Formability: It has good formability, suitable for various applications requiring high strength and corrosion resistance.
• Heat treatment: 5086 aluminum alloy is not strengthened by heat treatment. Instead, its strength is mainly increased through strain hardening or cold working.
• Non-magnetic: 5086 H32 aluminum alloy is non-magnetic, making it suitable for applications requiring non-magnetic materials.

Applications of 5086 H32 Aluminum Plate Sheet

5086 aluminum is widely used in shipbuilding applications, such as hulls and superstructures, ship ladders, pressure vessels, and armor plates for military vehicles.

• Ships (hulls, ladders)
• Offshore drilling platforms
• Cryogenic storage tanks and pressure vessels
• Military and other harsh environments

Typical Applications

Difference Between 5086 H321 and 5086 H32

• H321 is a stabilized temper with higher corrosion resistance, commonly used in shipbuilding applications requiring high marine classification standards.
• H32 is a medium-strength strain-hardened temper for general marine and industrial use.

5086 H32 vs H116

• H116 is a marine-specific temper with more stringent exfoliation and stress-corrosion resistance requirements.
• H32 has similar strength but lower certification requirements.

In the shipbuilding industry:

• Bottom plates and side plates of ships: mostly 5086-H116
• General structural plates: 5086-H32

5083 H32 vs 5052 H32

5086 H32 is a "balanced" aluminum alloy, achieving an excellent balance between corrosion resistance, medium strength, and workability. It is particularly suitable for applications that require long-term exposure to harsh environments while maintaining structural stability, making it an ideal material for marine, transportation, and outdoor structural fields.

5086 H32 vs 6061 T6

• For seawater environments: choose 5086 H32.
• For applications requiring high strength and heat-treatable properties: choose 6061 T6.

Comparison of 5086 with Similar Alloys

• Compared with 5083: Due to higher manganese content in 5083, the mechanical properties of 5086 are slightly lower, but its characteristics are comparable to 5083, making it a popular and cost-effective alternative.
• Compared with 5052: 5086 has higher strength than the more common 5052 alloy, making it suitable for more demanding structural applications.
