Ship structures are mostly used in harsh seawater medium and marine environment. Therefore, whether aluminum alloy is corrosion-resistant is one of the main symbols to determine whether it can be used as marine aluminum alloy. It is generally required that the marine aluminum alloy matrix and welded joints have no tendency of stress corrosion, spalling corrosion and intergranular corrosion in seawater and marine environment; Contact corrosion, crevice corrosion and marine organism adhesion corrosion shall be avoided as far as possible; Small uniform corrosion and pitting corrosion are allowed.
Marine aluminum plate 5083 is a typical antirust aluminum plate and a commonly used marine aluminum plate. Its wide application in the field of shipbuilding is inseparable from its good performance.
What are the advantages of 5083 marine aluminum 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 of steel or other alloy materials. This can reduce the weight of the ship and reduce energy consumption.
2. The high toughness, corrosion resistance and weldability of 5083 marine aluminum plate make it possible for strict ship type production. At the same time, marine aluminum plate can resist the corrosion of atmosphere, steam, water and other media in marine climate for a longer time, which is durable and more economical.
Generally speaking, the excellent marine climate resistance, especially seawater corrosion resistance of 5-series and 6-series aluminum magnesium alloys have been recognized by everyone. 5083 aluminum plate is a typical welding aluminum alloy with medium strength, good weldability, corrosion resistance and low temperature performance. It can be used as marine aluminum plate on the ship side.
