5086 Aluminum Sheet and Pipe for Boat Building

The shipbuilding materials were originally mainly steel. With the advancement of technology, marine aluminum plates are gradually used in yachts, fishing boats, jon boat, tug boat, high speed boats. And the level of all-aluminumization is gradually improving. In recent years, many countries have successfully built all-aluminum ships, covering hulls, decks, pistons, pumps, etc.

Because aluminum is light, corrosion-resistant and strong, its use in ship hull structures can significantly reduce the weight of the ship, lower the center of gravity and increase the load. And with the advancement of aluminum alloy metallurgical processes and welding methods, it has become the mainstream of advanced marine materials. The main aluminum alloys are alu 5086, 5083,5853,5059,etc.

From 1966 to 1971, the United States built 14 "Asheville" class high-speed gunboats. The main deck and bottom plate were made of 12.7mm thick 5086-H32 aluminum alloy, and the profiles were made of 5086-H112 aluminum alloy. Tugboats can also be made of aluminum alloy. The American "Sauter" tugboat hull is welded with 5083 and 5086 alloys, and the manufacturing time is about 30% shorter than that of a steel barge.

5086 aluminum plate, with a magnesium content between 3.5% and 4.5%, is a high-magnesium and non-thermally treatable alloy. Therefore, the strength of 5086 aluminum is higher than that of 5052 aluminum alloy, but the strength is slightly lower than that of 5083 aluminum alloy. Good welding results and excellent corrosion properties in seawater make 5086 sheet and 5086 aluminum pipe very popular in the construction of ship ramps, ship and yacht hulls.

Generally speaking, the commonly used of 5086 marine aluminum plates are O, H111, H112, H116, H321, etc. In terms of mechanical properties, 5086 aluminum sheet’s tensile strength tensile strength (MPa): ≧240 and conditional yield strength (MPa): ≧95, elongation10(%): ≧10, elongation 5(%): ≧12.

Haomei Aluminum can offer marine aluminum plates and extrusions of various thicknesses, widths and lengths like 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm. The large specification are also available such as 2*6 meters, 2*8 meters, 2*12 meter,etc. All our marine aluminum products are with classification society certification.
