As the global shipping industry’s demand for energy conservation, emission reduction, and load efficiency surges, aluminum alloy has become the first choice for hull materials due to its light weight, corrosion resistance, and high strength. Among many aluminum plates, 5083 aluminum plate and 5086 aluminum plate stand out due to their balanced performance, but how to choose between the two?
| Parameters | 5083 Aluminum Plate | 5086 Aluminum Plate |
| Tensile strength | 270-310 MPa(Higher pressure bearing capacity) | 240-280 MPa(Meet general needs) |
| Corrosion resistance | Excellent (long-term resistance to seawater erosion) | Excellent (almost the same as 5083) |
| Welding performance | Excellent crack resistance (complex welding possible) | Good (suitable for conventional welding process) |
| Lightweight effect | Weight reduction of 30%+ (compared to steel) | Weight reduction of 35%+ (thinner and more material-saving) |
| Cost | Higher (high performance premium) | Moderate (better cost performance) |
◆ Large ship structures: such as cargo ship bulkheads and warship decks, which need to withstand high loads and complex stresses.
◆ Strict welding requirements: Key parts such as hull keels and joints rely on high crack resistance welding.
◆ Long-term durability priority: Ocean-going ships need to resist decades of seawater corrosion and have lower maintenance costs.
◆ Small and medium-sized ship hulls: Yachts, speedboats, etc., pursue extreme lightweight to improve speed and fuel efficiency.
◆ Non-load-bearing parts: Cabin interiors, deck coverings, taking into account cost and weight reduction requirements.
◆ Short-term cost-sensitive projects: When the budget is limited, the performance is sufficient and the economy is better.
Clear requirements: ship size, load-bearing strength, budget range. Performance benchmarking: Refer to the comparison table above to filter the priority of core parameters. Manufacturer collaboration: Choose suppliers that provide material certification (such as DNV/ABS) to ensure compliance and reliability.Flait Aluminum is a professional marine grade aluminum plate supplier. Our marine aluminum plates have passed CCS, DNV, BV, ABS classification certifications. The product’s mechanical properties, welding performance and corrosion resistance are up to the ship standards. We continue to improve the production process, and now both aluminum plates have launched low-carbon process versions. Among them, the recycled aluminum content of 5083/5086 aluminum plates reaches 50%+, meeting ESG standards. At the same time, we use new anodizing technology to further improve corrosion resistance, thereby increasing the service life of the product by 20%. Whether you are pursuing the ultimate performance of 5083 aluminum plate, or the economical and lightweight 5086 aluminum plate, please feel free to contact our team!
