How to choose a ship 5083 aluminum plate manufacturer?

The 5083 aluminum plate is a representative product of the 5-series aluminum-magnesium alloy. It has excellent anti-rust ability, excellent weldability and good cold workability. The aluminum plate can adapt to the high corrosive environment of the sea for a long time, and is a widely used marine aluminum plate. The state of the 5083 aluminum plate for ships is usually in the state of H116/H321/H112. It is mostly thick plate and can be used for decks, engine pedestals, ship sides, and bottom plates of ships such as yachts, fishing boats, work boats, and sand transporting vessels.

Among many aluminum panel manufacturers, How to choose a ship 5083 aluminum plate manufacturer?

For marine aluminum panels, the certification of classification societies is very important. It is an affirmation of the 5083 aluminum plate, which can only be used to produce ships, offshore facilities and equipment after obtaining the corresponding certificate issued by the classification society.
Mingtai Aluminum’s 5083 aluminum sheet has passed the certification of CCS China Classification Society. Recently, it has passed the ABS American Classification Society certification. ABS has a wide range of business, including ships and marine engineering. ABS American Classification Society also has strict requirements on corporate qualifications. It requires enterprises to have complete production equipment, complete production capacity, establish a quality management system and operate effectively, and pass ISO9001 certification.

Mingtai 5083 aluminum plate meets four conditions for marine aluminum panels:

1.Excellent corrosion resistance. Since the ship plate is immersed in sea water for a long time and the environment is humid, the ship plate is required to have high corrosion resistance and can be used in harsh seawater medium and marine environment. Therefore, corrosion resistance is one of the main signs of marine alloys. The 5083 marine aluminum plate belongs to the AL-Mg alloy gold-plated aluminum plate. It is a typical rust-proof aluminum with excellent corrosion resistance.
2.High specific strength and specific modulus. The structural strength and size of the ship are closely related to the yield strength and elastic modulus of the material. Since the elastic modulus and density of the aluminum alloy are generally the same, the addition of alloying elements has little effect, so the yield strength is reduced within a certain range. The ship structure is powerful. High-strength aluminum alloys are often difficult to have both excellent corrosion resistance and weldability. Therefore, marine aluminum alloys are generally medium strength, corrosion resistant weldable alloys.

3.Excellent welding performance. At present, the main method used in the ship is the automatic argon arc welding method. The good weldability indicates that the crack formed by the aluminum alloy during welding tends to be small, that is to say, the aluminum alloy should have good welding crack resistance, because the shipbuilding conditions cannot pass again. Heat treatment restores lost weldability.
4. Marine 5083 aluminum plate has good cold and hot forming properties. Because the ship is manufactured by cold processing and hot processing, the marine aluminum alloy must be easy to process, no crack defects, and can still meet the strength and corrosion requirements after processing.
Mingtai Aluminum’s 5083 aluminum plate has complete specifications and excellent performance. It meets many requirements for marine aluminum plates. It has been exported to more than 30 countries and regions and has been successfully applied to ship decks, engine pedestals, ship sides, bottom plates and other components.
