5083 aluminum alloy sheet
5083 aluminum alloy sheet belongs to the Al-Mg-Si series alloy, with high magnesium content, which cannot be strengthened by heat treatment. But this alloy has an obvious anti-rust effect, so the aluminum sheet plays an important role in anti-rust and anti-corrosion. At the same time, 5083 alloy processed by 5083 aluminum sheet suppliers has high fatigue resistance, good machinability, and good anodizing effect.
5083 aluminum alloy features and applications
The shipbuilding industry has special requirements for aluminum alloy strength, corrosion resistance, and weldability. The main alloy element of 5083 aluminum alloy is magnesium, which has good forming processability, corrosion resistance, weldability, and strength that can also meet shipbuilding. Therefore, marine-grade aluminium 5083 mostly use 5000 series Al-Mg alloys. In addition, 5083 aluminum alloy can also be used in the manufacture of pressure vessels such as automobile manufacturing and liquid tank trucks.

Why is 5083 aluminum alloy used for marine aluminum?
1) 5083 aluminum coil sheet has the highest strength among non-heat-treatable aluminum alloys.
2) 5083 aluminum sheet has good corrosion resistance and excellent performance in seawater.
3) 5083 aluminum is easy to process, the sheet can be bent, and the welding performance is excellent.
4) 6000 series alloys will cause intergranular corrosion in seawater, and the corrosion resistance is not as good as 5000 series aluminum and is not suitable for use on ships.
5) The 7 series alloy has poor corrosion resistance and is not suitable for the marine environment.
What is the difference between 5052 vs 5083
The difference between the 5083 aluminum alloy and the 5052 is not much from the point of view of oxidation, the main difference is the mechanical properties. In terms of tensile strength and yield strength, the 5083 h116 is much stronger than the 5052 aluminum sheet. In terms of characteristics and uses, the 5052 alloy aluminum sheet has good forming processability, fatigue strength, and medium static strength. Besides, 5052 alloy is useful for manufacturing aircraft fuel tanks, oil pipes, sheet metal parts for ships, and hardware products. 5083 h24 aluminum sheet is used on occasions where high corrosion resistance, good weldability, and medium strength are required.
What should be paid attention to when bending the 5083-h116 aluminum sheet?
1)The temper of 5083 aluminum alloy
The bending effect of 5083 aluminum alloy depends on the temper, the temper of higher hardness, it is easy to break when bending, H18 super hard temper is not suitable for bending, the temper suitable for bending are O temper, H111, H112, H114, H24, H32, h34, etc.
2) The thickness of 5083 aluminum sheet
Aluminum sheets that are too thick are not easy to bend. This is common knowledge in the industry. Try to use thinner aluminum sheets.
3) The size of the bent R angle.
The greater the bending R angle, the higher the success rate, so try to increase the bending R angle as much as possible.
4) The direction of the lines when bending.
The bending direction should be perpendicular to the grain direction and cannot be parallel. The aluminum sheets parts that need to be brushed are best to be drawn after bending if the process allows, otherwise the probability of bending and breaking will increase.
Mingtai Al. Co., Ltd 5083 aluminum sheet suppliers can be regarded as the representative product of 5000 series marine aluminum sheet plate, the status is O, H111, H112, H116, H32, and so on. Among them, the 5083-h116 aluminum sheet has good formability and high fatigue resistance. And it is generally used as the main structure for manufacturing the hull. Others such as 5052, 5086, 5454, 5456, etc. are also used in hull structures or pressure vessels, pipelines, hulls, and decks.
