With the rapid development of Turkey’s shipbuilding industry, the lightweight of ships has been paid more and more attention. Aluminum alloy has the characteristics of low density, high strength, good rigidity and excellent corrosion resistance. It is widely used in the construction of ships with strict weight requirements, which can reduce the weight of ships by 15%-20%. Mingtai 5083 marine aluminum plate is exported to Turkey.
Common marine aluminum plates include 5 series and 6 series aluminum alloys. 5083 aluminum plate has attracted much attention in the field of shipbuilding due to its excellent performance and wide range of applications. As a kind of Al-Mg alloy, 5083 aluminum plate has excellent corrosion resistance, weldability and cold working properties. Its main alloying element is magnesium, which makes 5083 aluminum plate not only have good forming and processing performance, but also have medium strength, meeting the dual requirements of material strength and corrosion resistance in shipbuilding.
The yield strength and elastic modulus of the material are the most basic parameters for calculating the strength of ship structures and determining the structural dimensions. However, it is usually difficult for high-strength aluminum alloys to have excellent corrosion resistance and weldability at the same time. Therefore, aluminum alloys for ships are generally selected from aluminum alloys with medium strength and corrosion resistance and weldability. In addition, cast aluminum alloys also have certain applications in the field of ships.
The good weldability of aluminum alloys means that the tendency of aluminum alloys to form cracks during welding is small, that is, aluminum alloys have good welding crack resistance, and the performance of welded joints does not change much after welding. Because the performance lost due to welding cannot be restored by re-heat treatment under shipbuilding conditions, this is one of the important characteristics of marine aluminum alloys that is different from other structural aluminum alloys.
Ship structures are mostly used in harsh seawater media and marine environments. Therefore, whether aluminum alloys are corrosion-resistant is one of the main signs that determine whether they can be used as marine aluminum alloys. Generally, it is 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 environment; contact corrosion, crevice corrosion and marine biological attachment corrosion should be avoided as much as possible; small uniform corrosion and pitting corrosion are allowed.
During the construction process, ships must undergo cold processing (such as folding, curling, roller bending, stamping, etc.) and hot processing (such as hot bending, pyrotechnic correction, etc.). Therefore, it is required that marine aluminum alloys are easy to process and form, and no defects such as cracks are generated during processing. After processing, they can still meet the performance requirements such as strength and corrosion resistance.
5083 aluminum plate has the characteristics of small specific gravity and elastic modulus, corrosion resistance, weldability, easy processing, non-magnetic and good low-temperature performance, and has become one of the important materials in the field of shipbuilding. These advantages have made it develop rapidly in the application of ships, and the future prospects are broad.
