Aluminum plate for shipbuilding can divided into aluminum deforming and aluminum casting. aluminum-magnesium alloy, aluminum-magnesium-silicon alloy and aluminum-zinc-magnesium alloy are widely used in shipbuilding. There are some special requirements of strength, corrosion resistance and weldability for shipbuilding material, so the series 5xxx aluminum-magnesium alloy has a wide range of applications in shipbuilding.
What is the features of series 5xxx? Series 5xxx aluminum plate has three products that used in shipbuilding, there are 5083 aluminum plate, 5086 aluminum plate and 5454 aluminum plate, and the 5083 aluminum plate is the representative products of series 5xxx.
Status of 5083 aluminum plate: -O, -H111,-H112,-H116,-H321,etc.
Content (WT%): Si≤0.40，Cu≤0.10，Mg 4.0～4.9，Zn≤0.25, Mn 0.40～1.0, Ti≤0.15, Cr 0.05～0.25, Fe 0～0.400.
Features: medium strength, good corrosion resistance and formability, high fatigue resistance.
5083 aluminum plate is widely used in the main structure of the hull, and 5052 aluminum plate, 5086 aluminum plate, 5454 aluminum plate are widely used in pressure vessels, pipes, hulls, decks and other parts.
Series 6xxx alloy will occurs intergranular corrosion in seawater, so it used in ships superstructure, and poor corrosion resistance is the disadvantage of series 7xxx alloy , so the use of series 7xxx is limited, in summary, series 5xxx is the most promising aluminum alloy for shipbuilding .
