5086 Aluminum Sheet

Unique introduction of 5086 aluminum sheet

5086 aluminum sheet is a high-strength, corrosion-resistant al-mg alloy, widely used in aerospace, transportation, architectural decoration and other fields. Its main components are aluminum, magnesium, silicon, manganese, chromium and other elements, among which magnesium has the highest content, and has excellent mechanical properties and welding properties.

Al-mg alloy and Al-mn alloy are collectively called rust-proof aluminum, because the alloy components between the two have increased their corrosion resistance. The representatives of aluminum-manganese alloy are 3003, 3004, 3105, and the al-mg alloy is 5005 5252 5251 5050 5052 5754 5083 5056 5086 according to the content of magnesium alloy.

Typical uses: used in occasions that require high corrosion resistance, good weldability and medium strength, such as ships, automobiles and aircraft panels that can be welded; pressure vessels, refrigeration equipment, TV towers, detection equipment, transportation equipment, missile parts, armor, etc. that require strict fire protection.

Common temperings of 5086 aluminum sheet

According to different application requirements, the mechanical properties of 5086 aluminum sheet can be adjusted through different heat treatment states. Common supply states include but are not limited to the following:

• O (annealed): The material in this state has been fully annealed, has the best plasticity and lower strength, and is suitable for applications that require good formability.
• H112 (work hardening): The state that has been cold worked without heat treatment has higher strength and hardness, but relatively poor plasticity.
• H116: This is a higher degree of work hardening state, with higher strength and hardness than H112.
• H32: After a certain degree of cold working, partial annealing is performed to obtain a balance between moderate strength and good plasticity.
• H321: Similar to the H32, but after stabilization treatment, it helps to reduce performance changes caused by aging.
• H34: Stronger than the H32, it is obtained by a larger degree of cold working combined with appropriate heat treatment, and has higher strength.
• H36: Stronger than H34, suitable for applications that require higher strength.
• H38: This is one of the highest work hardening levels, providing extremely high strength, but may sacrifice some ductility.

Choosing the right 5086 aluminum sheet state depends on the specific application requirements, such as the strength, ductility, corrosion resistance and other specific properties of the material required. For example, in applications that require good formability, O or H32 states may be selected, while in the case of seeking higher strength, H34 or H36 states will be selected.

5086 aluminum sheet h32 elongation

5086 aluminum sheet is a common aluminum alloy material, and common states include H32.

H32 refers to aluminum alloy after heat treatment and cold working, which has certain strength and ductility. Elongation is a measure of the ability of a material to produce plastic deformation under stress, usually expressed as a percentage. For 5086 aluminum sheet H32, its elongation is usually between 15% and 25%, and the specific value depends on factors such as the specific manufacturing process of the material, heat treatment temperature and degree of cold working.

In general, 5086 aluminum sheet in H32 has high ductility and is suitable for applications that require a certain plastic deformation ability, such as shipbuilding, aerospace, and automobile manufacturing. At the same time, the elongation is also affected by external conditions such as temperature and strain rate, so actual testing is required in specific projects to obtain accurate data. In general, the elongation of 5086 aluminum alloy H32 is at a high level, which is suitable for some engineering applications that require high plastic deformation of materials.

Effect of 5086 aluminum alloy on performance

The state of 5086 aluminum alloy has an important influence on its performance. Different states have different mechanical properties, corrosion resistance and processing properties. For example, 5086 aluminum alloy in O has good plasticity and weldability, but low strength; while 5086 aluminum alloy in H state has high strength and corrosion resistance, but poor plasticity and weldability. Therefore, in practical applications, it is necessary to select the appropriate 5086 aluminum alloy state according to the use requirements of the parts.

5086 vs 5083 aluminum

Both 5086 aluminum alloy and 5083 aluminum alloy are members of the 5000 series aluminum alloys. They both contain magnesium as the main alloying element, so they both have good corrosion resistance, weldability and certain strength. However, there are some differences between the two aluminum alloys in chemical composition, physical properties and application scenarios. Here are the main differences between 5086 and 5083 aluminum alloys:

Chemical composition

• 5083 aluminum alloy: usually contains about 4.0% to 4.9% magnesium, and less than 0.4% manganese. This combination provides high strength and good weldability.
• 5086 aluminum alloy: The magnesium content is slightly lower than 5083, generally between 3.0% and 3.6%, and the manganese content is also relatively low. This makes 5086 aluminum alloy have slightly lower strength while maintaining good corrosion resistance.

Physical properties

• Strength: The tensile strength and yield strength of 5083 aluminum alloy are generally higher than those of 5086 aluminum alloy, which makes 5083 more suitable for applications that require higher strength.
• Corrosion resistance: Both have good corrosion resistance, but 5086 may show better corrosion resistance in certain environments, especially in seawater.
  Weldability: Both materials have good weldability, but 5083 is slightly better in terms of performance retention after welding, especially under high strength requirements.

Application scenarios

• 5083 aluminum alloy: Due to its high strength and good weldability, 5083 is often used in shipbuilding (such as hulls), truck frames, bridges, pressure vessels, and aerospace.
• 5086 aluminum alloy: Because of its good corrosion resistance and moderate strength, 5086 is suitable for occasions with high requirements for corrosion resistance but not particularly high requirements for strength, such as ship outfitting, building decoration materials, refrigerated truck bodies, etc.

In general, 5083 aluminum alloy is known for its higher strength and stability after welding, while 5086 aluminum alloy is known for its excellent corrosion resistance and formability. Which material to choose depends on the specific application requirements, including the required strength level, corrosion resistance requirements, and processing conditions.
