Performance and application of 5000 series marine aluminum p

Writer:Admin   Time:

    Because of the special requirements for strength, corrosion resistance and weldability of marine aluminum plate, the aluminum magnesium alloy, aluminum magnesium silicon alloy and aluminum zinc magnesium alloy are mostly used in the aluminum plate of ship, 5 Series Al Mg alloys are the most widely used in ships. The 5 series marine aluminum plates are mainly 5083, 5086, 5456.

    Why does the ship use the 5 series in the aluminum plate?

    The intergranular corrosion of 6 series alloys occurs in seawater, so the superstructure of ships is used more. The disadvantage of the 7 series alloys is poor corrosion resistance, so the application scope is limited. To sum up, the 5 series aluminum plate is the most widely used and most promising aluminum plate product at present.

    5083 aluminum plate can be considered as the representative product of 5000 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: less than 0.15 chromium 0.25 iron 0.25 iron 0.4005083 aluminum plate It has moderate strength, good corrosion resistance and formability, and high fatigue resistance. It is generally used as the main structure of ship. Others such as 5052, 5086, 5454, 5456, etc are also used in hull structures or pressure vessels, pipes, ships and decks.

    Generally speaking, the thickness of the plate aluminum is determined by the structure of the hull, the specification of the ship and the use position. In the light of the light weight of the hull, the plate is generally used as far as possible. However, the depth of the plate corrosion should be considered in the time of use, and the plate with more than 1.6mm or more than 30mm is usually used. Some special specifications are also used according to the shipyard contract. In order to prevent skidding, the deck is made of planks.

    From the development of marine aluminum plate, many aluminum manufacturers in China have begun to focus on the research and development of 5 series and 6 series of aluminum plates, increasing the scientific research, expanding the production scale, and marching into the high-end manufacturing market.
