The fatigue strength of aluminum plate is a key consideration in shipbuilding

In the aluminum processing industry, marine aluminum plate is one of the emerging fields of aluminum alloy products, and it is also the key direction of transformation and upgrading for many domestic aluminum plate manufacturers at present. Marine aluminum plate is mainly 5 series and 6 series aluminum plate, the main models are 5052 aluminum plate, 5083 aluminum plate, 5454 aluminum plate, 5754 aluminum plate, 5086 aluminum plate, 6061 aluminum plate, etc. They all have common characteristics, that is, good corrosion resistance.

shipbuilding aluminum plate

Marine materials need to focus on fatigue strength, marine aluminum plate should have high stress and low fatigue cycle, while welding performance should be good. 5 series and 6 series aluminum alloy has high strength and low toughness fracture characteristics, very suitable for hull structure manufacturing. In shipbuilding aluminum plate, 5052 aluminum plate is mainly used for superstructure, auxiliary components, small ship hull, ship sheet metal parts, etc.; 5083, 5086 aluminum plate is used for the main structure of ship hull; 5454 aluminum plate is mainly used for ship hull structure, pressure vessel, pipeline, etc.; 6061 aluminum plate is mainly used for ship superstructure, bulkhead structure, frame and other parts.

Marine aluminum plate meets the development demand of energy saving, emission reduction and light weight, and the advantages are very obvious. Firstly, the specific gravity of aluminum alloy is small, which can reduce the ship weight, save energy and increase the load capacity. Secondly, aluminum alloy has good corrosion resistance and is durable. In addition, the processing and molding of aluminum alloy is good. Finally, aluminum alloy is easy to recycle, safe and environmental protection.
