News Details

With the development of the times, the material of the hull is from steel plate to aluminum plate. Marine grade aluminium plate is a necessary material for shipbuilding. For shipbuilding enterprises, it is extremely important to choose a marine grade aluminium plate with excellent corrosion resistance. The marine grade aluminium plate produced by the aluminum industry has been certified by DNV and CSS. With excellent performance and large-scale production strength, it is deeply loved by the global shipbuilding industry.

1. Types of marine grade aluminium plate


Marine grade aluminium plate is divided into many types, the following lists some commonly used marine grade aluminium plate.


5083 marine grade aluminium plate


5083 marine grade aluminium plate has good corrosion resistance and weldability, as well as medium strength, beautiful surface after anodizing, low density, high tensile strength, high elongation, widely used in the marine field, can be processed into ship parts And wire clamps, suitable for manufacturing ships sailing in seawater or highly corrosive waters.


5052 marine grade aluminium plate


5052 marine grade aluminium plate and 5083 marine grade aluminium plate are similar in performance, have good forming performance and corrosion resistance, and are suitable for manufacturing ships sailing in fresh water.


7075 marine grade aluminium plate


7075 marine grade aluminium plate has extremely high strength, good corrosion resistance and oxidation resistance. It also has good workability and wear resistance. 7075 marine grade aluminium plate is stress-relieved and will not be deformed or warped after processing. Qu, after ultrasonic detection, can ensure no trachoma, impurities.


6061 marine grade aluminium plate


6061 marine grade aluminium plate has excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, toughness, easy polishing, coating, and excellent oxidation effect.


In addition, there are various marine grade aluminum plates such as 2024 marine grade aluminum sheet and 1060 marine grade aluminum sheet. As a shipbuilding material, aluminum plate has many superior properties, and its application in the field of shipbuilding is becoming more and more extensive. Ships are developing in the direction of aluminum material. Marine grade aluminum plate is a promising material.

2. Advantages of marine grade aluminium plate


Marine grade aluminium plate has high specific strength and specific modulus


The yield strength and elastic modulus of the material are the most basic parameters for calculating the structural strength of the ship and determining the structural dimensions. Since the elastic modulus and density of various marine grade aluminium plates are almost the same, and adding a small amount of alloying elements or changing the heat treatment state has little effect on them, so improving the yield strength within a certain range is beneficial to reduce the weight of the ship structure. Generally The density of marine grade aluminium plate is about 2.7~2.8/cm3, and the elastic modulus is about 70~73GPa.


Marine grade aluminium plate has excellent welding performance


For ships, the use of welded connections has obvious advantages over the use of riveted connections. Therefore, the welded connection method has been widely used in shipbuilding, basically replacing the riveted structure. At present, automatic argon arc welding is mainly used in the construction of aluminum ships. Marine grade aluminium plate has good weldability, and the tendency to form cracks during welding is small.


Marine grade aluminium plate has excellent corrosion resistance


Ships are mostly used in the marine environment, so the corrosion resistance of marine grade aluminium plate is one of the main standards. It is generally required that marine grade aluminium plate has no tendency to stress corrosion, spalling corrosion and intergranular corrosion in seawater and marine environments.


Marine grade aluminium plate has good cold and hot forming properties


The ship is subjected to cold processing (such as hemming, hemming, roll bending, stamping, etc.) and hot processing (such as hot bending, pyrotechnic orthopedics, etc.) during the construction process. Therefore, the marine grade aluminium plate is required to be easy to process and form, and no defects such as cracks are generated during processing, and the requirements of strength and corrosion resistance can still be met after processing.
