Marine Grade 5086 Aluminum Sheet

Generally, marine grade aluminium needs to have high specific strength and specific modulus, that is, medium strength, corrosion resistance and weldability. At the same time, it also needs to have excellent cold and hot forming performane for the thip is to be subjected to various treatments of cold working and hot working.

The marine aluminum plate must be easy to form, not crack, and still meet the strength and corrosion resistance requirements after processing. The common chosen alloys are 5052,5252, 5454, 5754, 5083, 5086, 5059, etc.

The magnesium content of the 5052 alloy is lower; the magnesium content of the 5154, 5454, and 5754 alloys is moderately low; the magnesium content of the 5083 alloy is moderately high; the magnesium content of the 5086 alloy is moderately low; the magnesium content of the 5059 alloy is the highest.

Many countries use Al-Mg alloys as hull structural materials. From 1966 to 1971, the United States built 14 "Asheville" high-speed gunboats. The main deck and bottom plate were made of 5086-H32 aluminum alloy with a thickness of 12.7mm, and the profiles were made of 5086-H112 aluminum alloy. In addition, 5052 alloy aluminum plate and 5454 aluminum alloy were also used for deck.

5086-H32 aluminium sheet with a thickness of 0.45-12.7mm is a popular choice for hull making. The smaller boats using riveted construction of 5052 or 6061 alloy, and larger custom yachts using all-welded construction in 5086. 5086 aluminum sheet is also used for bulkheads, fuel tanks and cabins.

5086 aluminum sheet belongs to the 5 series Al-Mg alloy, and the magnesium content generally does not exceed 7%. As the magnesium content increases, the strength of the alloy will increase, while the plasticity will decrease.

It is usually used in the annealed state, cold work hardening or semi-cold work hardening state. Due to the effect of magnesium, the density of 5086 anti-rust aluminum plate is higher than that of other aluminum plates, and it has very good corrosion resistance.
