5052 5086 Aluminum Sheet for Metal Fishing Boat
The aluminum alloys used in marine engineering include 5052 (5A02), 5252, 5154, 5454, 5754, 5083, 5086, 5059, 7A33 alloys, etc. The magnesium content of the marine grade aluminum 5052 is low; the magnesium content of the Al5086 is medium to low; the magnesium content of the 5059 alloy is the highest.
The Norwegian Shipbuilding Association stipulates the use of 5454 aluminum alloy, and the tensile strength of its plate is the same as that of 5086 aluminum alloy. In the United States, 5456 aluminum alloy is mainly used, but recently 5086-O aluminum alloy sheet and 5086-H111 aluminum alloy extruded profile are used in high-speed boats and metal fishing boat.
5086 aluminum sheet belongs to the Al-Mg alloy and the magnesium content generally does not exceed 7%. With the increase of the magnesium content, the strength of the alloy will increase, and the plasticity will decrease.
The 5086 anti-rust aluminum plate is usually used in the annealed state, cold hardening or semi-cold hardening state. Due to the effect of magnesium, the density of 5086 aluminum plate is much higher than that of other aluminum plates, and it has very good corrosion resistance.
5052 aluminium sheet is also often used for the aluminum fishing boat. The Mg content of 5052 aluminum alloy is 2.2%-2.8%. Its common temper is 5052 h34. It has the characteristics of light weight, medium strength, good corrosion resistance and weldability, and easy processing and forming. Among its mechanical properties, the tensile strength is can reach 215-265Mpa, and the elongation is over 5%. Under different work hardening and heat treatment states, the mechanical properties will be different.
Compared with the pure aluminum plate, the hardness of 5052 aluminum is 100% higher than that of 1060 aluminum alloy. At the same time, the elongation is also increased by 12-20%. Due to the effect of alloy elements, the corrosion resistance of 5052 aluminum plate is more obvious.
Compared with 6061 aluminum plate, the corrosion resistance of 5052 aluminum sheet is better, the heat transfer is similar, and the melting point is not much different that 6061 aluminum’s is a little higher.
But in terms of performance, 6061 is better than 5052 in terms of yield strength, but 5052 aluminum is better in terms of elongation. If it is a profile, 6061 alloy has an advantage, but 5052 is has better performance in the form of sheet metal.
