5083 marine grade aluminum plate belongs to 5xxx Al-Mg alloy. It is a typical rust-proof aluminum plate with good corrosion resistance, excellent weldability and good cold workability. It cannot be strengthened by heat treatment. Many speedboats are built with 5083 aluminum alloy.
Mg plays a major strengthening role in 5083 alloy. The main strengthening phase of the alloy is (Mg5Al8) phase, and Mg has a certain solid solution strengthening effect. As the Mg content increases, the strengthening phase in the alloy also increases. Because the strengthening phase is bone-like in the eutectic structure, the hardness is high. The increase in strengthening phase leads to an increase in alloy strength.
The main tempering of 5083 aluminum alloy are O, H12, H14, H16, H18, H19, H22, H24, H26, H28, H32, H34, H36, H38, H111, H112, H114, H116, H321, etc. The most common ones are H112, H116 and H321, which are widely used in the production of tanks, automobile fuel tanks, bus body panels, shipbuilding, etc.
Typical Mechanical Properties of 5083 Aluminum Alloy
| Temper | Tensile Strength (KSI) | Yield Strength (KSI) | Elongation (%) |
|---|---|---|---|
| H111 | 43 | 23 | 10 |
| H116 | 46 | 33 | 10 |
| H321 | 46 | 33 | 10 |
5083 H111 vs H116 vs H321 Tempers
| Temper | Features | Strength | Typical Applications |
|---|---|---|---|
| 5083 H111 | Soft strain-hardened temper with minimal cold working. Offers good plasticity and excellent weldability. | Relatively low strength. Suitable for applications not requiring high mechanical strength. | Ships, vehicles, architectural structures where formability and ductility are needed. |
| 5083 H116 | Specially controlled strain-hardened condition with enhanced corrosion resistance and mechanical strength. | Higher than H111. Suitable for more demanding environments. | Marine environments, ship hulls, offshore structures requiring good strength and corrosion resistance. |
| 5083 H321 | Thermally stabilized condition with excellent corrosion resistance and improved strength through special heat treatment. | Generally the strongest among the three. Ideal for extreme environments. | Pressure vessels, high-performance marine structures, aerospace, and other demanding industrial applications. |
