5083 Aluminum Sheet is renowned for its exceptional performance in harsh situations. 5083 Aluminum is extremely resistant to corrosion in marine and industrial chemical conditions.
Alloy aluminum 5083 maintains its strength even after welding. It possesses the highest strength of any non-heat treatable alloy, however it is not recommended for temperatures exceeding 65°C.
5083/5086 aluminum sheet is stronger than 5052 aluminum sheet and has superior corrosion resistance, particularly saltwater corrosion resistance. It is easy to shape, stamp, and weld.
5083 aluminum sheet is an Al-Mg-Si aluminum alloy. Its major constituents are magnesium, silicon, and aluminum. With more than 4.0% magnesium, the 5083 aluminum plate has good resistance to rectification and is easy to weld. Copper increases the conductivity of the 5083 aluminum plate to 28%.

Why 5083-H116/H321 Aluminum Sheet Is Often Used in Ships
5083-H116 and 5083-H321 aluminum plates are commonly selected for the underwater sections of ships due to their excellent corrosion resistance.
5083-H116 Aluminum Sheet
Compared with H111 and H112 tempers, 5083-H116 and H321 offer superior corrosion resistance, making them more suitable for harsh marine environments. Although the production temperatures for H116 and H321 differ slightly, both deliver significantly better corrosion performance than other tempers.
Advantages of 5083 Aluminum Sheet for Shipbuilding
Lightweight for Improved Efficiency
The low density of 5083 aluminum helps reduce the ship's overall weight, which lowers fuel consumption, enhances stability, and improves maneuverability and speed.
Excellent Corrosion Resistance
Its outstanding resistance to seawater corrosion helps reduce maintenance costs and prolongs service life.
Good Processability
5083 aluminum sheet offers excellent forming performance and can be processed through cutting, stamping, cold bending, and forming. This supports lightweight structural design and efficient fabrication.
Superior Weldability
It welds easily and requires fewer weld seams, enhancing structural reliability.
Rust-Resistant Performance
5083 aluminum's anti-rust characteristics make it ideal for wet or marine conditions. Tempers such as O, H111, H112, H116, and H321 are widely used in shipbuilding, especially 5083-H321.
5083 Aluminum Sheet in Different Tempers
5083 aluminum alloy is available in multiple tempers, each with different mechanical properties.
These tempers are achieved by fully annealing the sheet and then rolling it to the desired temper, rather than heat treating.
H116 and H321 are commonly used in ship and boat construction.
O, H32, and H38 are often used in the automotive and general industrial sectors.
When the thickness exceeds 40 mm, the performance of H116 and H321 decreases. The minimum tensile strength is 285 MPa, and the minimum yield strength is 200 MPa.
Elongation values for H116 and H321 vary according to thickness and measurement gauge. Refer to ASTM B928M for detailed specifications.
