Marine aluminum alloys are generally used for shipbuilding. The use of medium-hard aluminum alloy materials both has corrosion resistance and certain processing strength. At the same time, the ships can be made entirely of aluminum alloy materials after heating or welding.
En 5083 aluminum belongs to the aluminum-magnesium alloy series. Among them, Mg is the main strengthening element, which plays a certain role in solid solution strengthening. Its corrosion resistance and strength are suitable for shipbuilding. It can be used for the hull and floor of the boats.
5083 aluminum plate is an important component of the 5000 series aluminum alloys. Due to its high strength, strong corrosion resistance, easy processing and welding, it is mostly used in shipbuilding, and it is also called marine aluminum plate. It is the most representative product among many marine aluminum sheets. The 5083 aluminum plate has stable performance, and it can resist corrosion well in environments such as seawater and steam.
The 5000 series aluminum alloys are widely used in the field of marine engineering because of its excellent corrosion resistance. In shipbuilding, 5083 and 5086 aluminum alloys are used for shell structures, and 5052 and 5454 aluminum alloys are used to make ship decks and upper outfitting panels.
In the process of ocean transportation, liquefied natural gas (LNG) storage tanks have strict requirements on material performance, and it is necessary to ensure that the strength, mechanical properties and corrosion properties of the material are not affected at low temperature. 5083 aluminum alloy has the performance to meet the above conditions at the same time. It is the main manufacturing material for offshore low-temperature storage devices such as combustible ice and natural gas.
Aluminium 5083h111, h112, h116 and h321 are often used on the hulls of yachts, cruise ships, and fishing boats. The use of 5083 aluminum plate s not only significantly lighter, but from the perspective of ship designers, ships made of aluminum plates can have faster speeds and longer service life under the same power conditions.
Aluminum alloys are also used on barges. In 1964, an all-aluminum barge was built in the United States. The aluminum materials used exceeded 180 tons. The chosen aluminum alloy is 5083 aluminum. The cargo capacity is 14% higher than that of steel barges.
Tugboats can also be made of aluminum alloy. The hull of the American "Sauter" tugboat is welded with 5083 and 5086 alloys, and the manufacturing time is about 30% shorter than that of steel barges.
