The application of 5059 marine aluminum plate on the side of the ship

Ship structures are mostly used in harsh seawater media and marine environments, so whether aluminum alloys are resistant to corrosion is one of the main indicators to determine whether they can be used as marine aluminum alloys. It is generally required that the marine aluminum alloy matrix and welded joints have no tendency to stress corrosion, exfoliation corrosion and intergranular corrosion in seawater and marine environments; contact corrosion, crevice corrosion and marine organism adhesion corrosion should be avoided as much as possible; small uniform corrosion and spot corrosion are allowed. corrosion.


5059 marine aluminum sheet plate is a typical anti-rust aluminum plate, and it is also a commonly used marine aluminum plate. The reason why it is widely used in the field of shipbuilding is inseparable from its good performance.

What are the advantages of 5059 marine aluminum sheet plate?

1. The low density, high strength, high rigidity and corrosion resistance of aluminum reduce the weight of aluminum ships by 20% compared with ships built with steel or other alloy materials. This reduces the weight of the ship and reduces energy consumption.

2. The high toughness, corrosion resistance and weldability of 5059 marine aluminum sheet plate provide the possibility for strict ship type production. At the same time, the marine aluminum sheet can resist the corrosion of the atmosphere, steam, water and other media in the marine climate for a longer time, and is durable and more economical.

In general, the excellent marine weather resistance of the 5 and 6 series aluminum-magnesium alloys, especially the seawater corrosion resistance, has been recognized by everyone. Among them, the 5059 marine aluminum sheet plate is a typical aluminum alloy for welding, with medium strength, good weldability, corrosion resistance and low temperature performance, and can be used as a marine aluminum plate on the side of the ship.
