5083 vs 5086 aluminum – marine aluminum

5083 vs 5086 is the main alloy of aluminum plates for ships. In shipbuilding, 5083 and 5086 aluminum plates are often used to process multiple parts such as the hull, console, and deck. These two alloys are more commonly used, and the alloy state is rich, and there are many types of specifications.

The reason why 5083 and 5086 aluminum are used as marine aluminum

The marine environment is special, and the hull of the ship needs to be immersed in sea water for a long time, so the requirements for the material of the ship plate and sheet metal are very high. Because 5083 aluminum sheet and 5086 aluminum sheet  have excellent corrosion resistance, excellent welding performance, and good forming performance and strength. Therefore, the two have good application effects in the field of marine vessels.


What 5083 vs 5086 aluminum has in common

Both 5083 aluminum and 5086 aluminum belong to 5 series aluminum alloy sheet, which are widely used in anti-rust aluminum. Both are used in occasions that require high corrosion resistance, good weldability and medium strength, such as weldable parts for ships, automobiles and aircraft plates. And pressure vessels, refrigeration devices, TV towers, installation equipment, transportation equipment, etc. that require strict fire protection.


The difference between 5083 and 5086 aluminum

The main difference between 5083 and 5086 aluminum is the difference in chemical composition content and the difference in mechanical properties.

The content of each chemical component of 5083 aluminum plate: Si: ≤0.4 Cu: ≤0.1 Mg: 4.0–4.9 Zn: 0.25 Mn: 0.40–1.0 Ti: ≤0.15 Cr: 0.05–0.25 Fe: 0.4

The content of each chemical component of 5086 aluminum plate: Mg: 3.5~4.5 Zn: ≤0.25 Mn: 0.20~0.7 Ti: ≤0.15 Cr: 0.05~0.25 Fe: 0.000~0.500

5083 mechanical properties: tensile strength σb (MPa): 110-136 elongation δ10 (%): ≥20 annealing temperature: 415℃ yield strength σs (MPa) ≥110

5086 Mechanical properties: Tensile strength σb (MPa): ≥240 Conditional yield strength σ0.2 (MPa): ≥95 Elongation δ10 (%): ≥10 Elongation δ5 (%): ≥12

Alloy temper of 5083 and 5086 aluminum when used as marine aluminum

In shipbuilding, H116 and H321 are most commonly used in 5083 and 5086. Ship plates in these two states have the best corrosion resistance and are more suitable for the underwater environment of the ocean than H111 and H112. Although the temperature of H116 and H321 ship plates is slightly different during the production process, the corrosion resistance is obviously better than other conditions.
