Marine Grade Aluminum AA 5086
In the development of the international marine economy, the performance and international certification of marine aluminum sheets are one of the important factors restricting the development of domestic aluminum enterprises.
It is precisely under such strict requirements that Haomei Aluminum has been placing large orders for marine aluminum sheets recently. In February, it gets an order from Türkiye customers for 63 tons of AA 5086 marine aluminum sheets.
Marine aluminum alloys have the advantages of light weight, good corrosion resistance, good processing and forming performance, and non-magnetic properties. At the same time, it has a certain yield ratio, high temperature strength, fatigue strength and elongation.
The high-temperature strength should ensure that the mechanical properties should remain unchanged when heated to 100 degrees Celsius, and the yield limit should not be reduced by more than 40% when heated to 250 degrees Celsius. Because marine aluminum sheets have been widely used in small and medium-sized passenger ships, yachts, speedboats, high-speed missile boats, patrol boats, destroyers.
At present, three alloys of 5083, 5086 and 5383 are mainly used in the hull structure, and their corrosion resistance, mechanical properties and welding performance are all good. These small boats have a weak point that is easy to break, but using aluminium alloy can well avoid such problems.
Marine grade aluminum 5086 properties
Generally speaking, the tempers of 5086 aluminum sheet is O, H111, H112, H116, H321, etc. In terms of mechanical properties, the 5086 aluminum plate’s tensile strength (MPa): ≥240, conditional yield strength (MPa): ≥95, elongation 10(%): ≥10 and elongation δ5(%): ≥12.
Hoamei Aluminum makes uses of the residual heat of "1+4" hot rolling coils to realize self annealing, which develops a "1+4" hot rolling short-process high-efficiency production technology for the production of 5xxx marine grade aluminum sheets, eliminating recrystallization annealing, cold rolling, intermediate annealing, cleaning, stabilizing annealing and other processes after hot continuous rolling.
That will shorten the production cycle by 3-7 days and the production cost is reduced by 50-140 dollars/ton. The 5086 aluminum plate’s mechanical properties, corrosion resistance, plate shape, surface quality and other quality indicators can meet the requirements of Det Norske Veritas (DNV.GL), American Bureau of Shipping (ABS), China Classification Society (CCS) and RINA.
