Aluminum Alloy Grade 5052 5086
Ships also need to consider their own weight when sailing at sea. One of the characteristics of aluminum alloy is its light weight and high strength, which can improve the portability of the ship. Under the same circumstances, the aluminum alloy ship’s speed is higher, fuel consumption is reduced, and the overall stability of the ship is increased. In addition, since the ship is light, it is also conducive to control room operation, thereby increasing the ship's capacity, providing more loading space, saving costs and increasing profits.
5052 alloy is a very popular aluminum alloy. 5052 aluminum plate is an Al-Mg alloy with excellent corrosion resistance and medium strength. It is suitable for the manufacture of economical aluminum alloy ships. 5052h32 is an annealing process that accounts for a large proportion of the entire use.
In the international code, 5052 marine grade aluminum can also be called almg2.5, which also means that the content of mg alloy (magnesium alloy) is around 2.5% (between 2.2-2.6), with low density (2.68), high strength, and strong machinability. It is an excellent product suitable for bending, stamping, stretching and other processing techniques.
Aluminum alloy yachts for freshwater lakes are mostly made of 5052-H32 or 5052-0 aluminum plates, while luxury yachts at sea are generally made of high-magnesium alloy 5083H116 or 5083H321 aluminum plates.
Among the 811.30t aluminum alloy used in the superstructure of the "Dewey", most of them are 5456 alloy thick plates and 5086 aluminum sheet. After aluminum components replace steel, unnecessary mass is saved. Of the total aluminum usage, about 20% is 5456 and 5086 alloys. 5086h32 aluminum sheet is a popular choice.
5086 aluminum is an aluminum-magnesium alloy, mainly magnesium alloy. It is strengthened not by heat treatment, but by strain hardening or cold working of the material. Heat treatment does not significantly affect strength, so 5086 aluminum sheet is easily weldable and retains much of its mechanical strength. Good welding results and excellent corrosion properties in seawater make 5086 very popular in the construction of ship ramps, small boat hull and yacht hulls.
