The selection of marine aluminium grades alloy materials is relatively strict, at present, aluminum alloy products such as 5083 aluminium plate, 5086 aluminium plate, 5454 aluminium plate, 5754 aluminium plate and 6061 aluminium plate are mostly used. In practical applications, the advantages of marine aluminium alloys are very obvious. First, the specific gravity is small, which can reduce the weight of the ship, save energy consumption, and increase the load capacity. Secondly, it has good corrosion resistance, reduces the cost of oiling, and prolongs the service life. The third is welding, processing and molding performance is good, which is beneficial to post-processing. The last, aluminum waste is easy to recycle and can be recycled, and at the same time, it will not burn and meet fire.

marine aluminium grades

In recent years, relying on strong advantages in aluminum alloy research and development, production and deep processing, technological innovation has been continuously accelerated, and aluminum alloy ships with more environmentally friendly materials and processes have become manufacturing advantages. Aluminum alloy ships are the third type of ship after steel ships and glass fiber reinforced plastic ships, and have been widely used in the market and vigorously developed. Although it cannot replace steel ships and glass ships at present, aluminum alloy ships have very strong development potential in terms of material life, energy saving and environmental protection. The marine grade aluminium has obtained China Classification Certification and DNV Det Norske Veritas Certification, which has laid a solid foundation for exploring the international market and further enhanced Haomei Aluminum marine grade plate market space in Europe, North America, Asia and Africa.


Marine aluminium grades plate is an emerging market for the research and development and application of aluminum plate products. Shipbuilding aluminum plate production capacity has also become an important indicator to measure the comprehensive strength of various aluminum processing enterprises. With the improvement of the domestic aluminum plate production process, the production scale of Haomei Aluminum, an enterprise in Henan Province, has gradually expanded, the marine aluminium grade alloys have become increasingly rich, and the product performance has reached the level. At present, Haomei Aluminum’s 5083 aluminum plate, 5086 aluminum plate, 5754 aluminum plate and other products have entered the shipbuilding market and are mainly used in ship decks, engine pedestals, ship sides, ship bottom outer plates and other components.
