There are special requirements for strength, corrosion resistance and weldability of <strong>marine
aluminum plate</strong>, so the aluminum magnesium alloy, aluminum magnesium silicon alloy and aluminum zinc magnesium alloy are mostly used in the
aluminum plate of ship, of which 5 Series Al Mg alloys are the most widely used in ships.<br>
</div>
<div>
The 5000 series marine
aluminum plates are mainly 5083, 5086, 5456 . The intergranular corrosion of 6000 series alloys occurs in seawater, so the superstructure of ships is used more. The disadvantages of 7000 series
aluminum alloys are poor corrosion resistance, so the scope of application is limited. To sum up, the 5000 series
aluminum plate is the most widely used and most promising
aluminum plate product at present.</div>
<div>
Among them, <strong>5086
aluminum plate</strong> can be considered as the representative product of 5 series marine
aluminum plates, such as O, H111, H112, H116, H321, etc.; 5083
aluminum alloy components are: aluminum Al: residue, silicon Si: 0.40, copper Cu: less than 0.10, Mg Mg:4.0 to 4.9, zinc Zn: < 0.25 manganese Mn:0.40 to 1 titanium Ti: < 0.15 chromium chromium 0.25 iron 0.25 iron 0.400 to 0.25; 50 83
aluminum plate has moderate strength, good corrosion resistance and formability, and high fatigue resistance. It is generally used as the main hull structure. Others such as 5052, 5086, 5454, 5456, etc. are also used in hull structures or pressure vessels, pipes, ships and decks.</div>
<div>
Generally speaking, the
aluminum plates of ships can be divided into deformed
aluminum plates and cast
aluminum plates according to the different manufacturing processes. The thickness of the <strong>plate aluminum</strong> is determined by the structure of the hull, the specifications of the ship and the use position. In the light of the weight of the hull, the
aluminum alloy plate is generally used as far as possible, but the depth of the plate corrosion should be considered in the time of use, and the plate with more than 1.6mm and the <strong>thick
aluminium plate</strong> on the 30mm should be used. Some special specifications are also used according to the shipyard contract. In order to prevent skidding, the deck is made of planks.</div>
