A Highlight of Marine Aluminum Sheet Grades Chart
5 series marine grade aluminium alloy is an aluminum alloy with magnesium as the main alloying element, belonging to the Al-Mg series alloy. This series of alloys has good corrosion resistance, weldability and medium strength, and is widely used in shipbuilding. In addition to the 5083 grade that we focus on, there are also 5086, 5052, 5059, etc.
5086 aluminum alloy
5086 aluminum’s strength is similar to that of 5083, and it can be used as an alternative material in some application scenarios. It has good processing performance and is easy to perform forming operations such as bending and stamping. It is often used to manufacture ship outer plates, decks and other parts. In the construction of some small ships with high requirements for material strength and corrosion resistance, such as high-end yachts, 5086 aluminum alloy can give full play to its comprehensive performance advantages to ensure the quality and beauty of the hull.
5052 Aluminum Alloy
5052 has good formability and corrosion resistance and is one of the most widely used 5 series aluminum alloys. Its density is about 2.68g/cm³, which is similar to 5083 aluminum plate in density. Its strength is relatively low, so it is usually used for structural parts that do not require high strength but pay more attention to formability and corrosion resistance, such as the production of ship interior decorative panels.
5059 aluminum alloy
5059 aluminum alloy is a high-strength 5 series aluminum alloy with a high magnesium content, which gives it excellent strength and hardness. In terms of corrosion resistance, 5059 also performs well and can adapt to the harsh environment of the ocean.
Due to its high strength characteristics, 5059 aluminum alloy is often used in key structural components of ships, such as keels, support frames, etc. These components need to withstand greater stress. 5059 aluminum alloy can ensure the stability and safety of key structures during long-term use of ships, providing a solid foundation for the normal navigation of ships.
Unique performance of 5083 aluminum plate
5083 aluminum plate is a star product among 5 series aluminum alloys. It has excellent corrosion resistance and can maintain good performance for a long time in the highly corrosive environment of seawater, which provides reliable guarantee for the long-term safe operation of ships. Its welding performance is excellent. During the assembly process of the hull, it can form a strong connection through welding to ensure the integrity of the hull structure. Moreover, 5083 aluminum plate also has good processing performance and can be processed into various shapes and specifications according to the different needs of ship construction.
Weight advantage of 5083 aluminum plate
In ship design and construction, weight is a core consideration. The density of 5083 aluminum plate is relatively low, about 2.66g/cm³. Let's take an aluminum plate with a length of 10 meters, a width of 2 meters, and a thickness of 15 mm as an example to calculate the weight. The 5083 aluminum sheet weight is 1000x200x1.5x2.66 = 798000g = 798kg.
Wide application of 5083 aluminum plate in ships
In actual shipbuilding, 5083 aluminum plate can be seen everywhere. In the field of small speedboats and yachts, its lightweight characteristics make the hull faster, while its good corrosion resistance ensures the beauty and durability of the hull in seawater environment. For large commercial ships, 5083 aluminum plate is often used in the construction of superstructures, which not only reduces the overall weight of the ship and lowers the center of gravity, but also improves the stability of the ship, reduces the shaking when sailing in wind and waves, and improves the safety of crew and cargo. In some special ships, such as scientific research ships, patrol boats, etc., the comprehensive performance of 5083 aluminum plate meets their strict requirements for structural strength, corrosion resistance and lightweight.
