5083 marine grade aluminum sheet metal
As known to all, 5083 marine grade aluminum sheet metal can be used in the manufacture of civil ships like yachts and vessels, but actually it can also be applied to aircraft carriers. An aircraft carrier is a behemoth. It is huge and well-built. As a highly maneuverable combat platform, it has an urgent need to reduce the weight of the structure by controlling material weight of various devices, especially the upper layer. Furthermore, the carrier rests and travels in the ocean, and it must be of strong resistance to seawater corrosion. The 5083 aluminum plate has a small specific gravity, which can reduce the weight of the ship, save energy, and increase the load. In addition, it has good corrosion resistance, reduces the cost of oiling, and extends the service life. There is also good welding and processing forming performance, which is conducive to later processing.
The application of marine aluminum sheets, including 5083 and 5xxx other alloys, in aircraft carriers is a global trend. Figures show that the amount of aluminum alloy material used for each foreign aircraft carrier is about 1,000 tons. For example, the US "Independence" (CVA62) aircraft carrier uses 1,019 tons of aluminum alloy; the "Enterprise" nuclear-powered aircraft carrier (CVA65) uses 450 tons of aluminum alloy; France More than 1,000 tons of aluminum alloy are used on the aircraft carriers "Fuxi" (R99) and "Crimenceau" (R98). The application of aluminum alloy on aircraft carriers is of great significance for reducing the weight of aircraft carrier structures, improving stability, airworthiness, and improving combat technical performance.
The 5083 marine grade aluminium sheet metal is applied to the following parts of an aircraft carrier: landing decks, huge lifts, a large number of piping systems, porthole covers, chandeliers, doors, compartment next doors, compartment decoration, furniture, kitchen equipment and some auxiliary machinery, etc. The four huge elevators of the USS Enterprise, which was commissioned by the U.S. Navy in 1961, were welded from aluminum-magnesium alloys. 5083 marine grade aluminum for aircraft carriers has a thickness ranging from 1mm to 50mm, and width up to 3800mm.
