Large Aluminum Sheet for Aluminum Boat Construction
With the rapid development of shipbuilding industry at home and abroad, the lightweight of ships is being paid more and more attention. Due to the low density, high strength and strong corrosion resistance of large aluminum sheet, it is very suitable for the harsh environment of the ocean.
From the perspective of ship designers, ships made of industrial aluminum sheet and profile can have faster speeds under the same power conditions and have longer service life. Therefore, the technology of the marine grade aluminum alloys for aluminum boat construction has got great improvement.
Four advantages
Excellent welding performance
Welding has more obvious advantages than riveting, because in shipbuilding, the properties lost due to welding cannot be recovered by re-heat treatment, while marine aluminum sheets have good welding crack resistance, and the performance of welded joints after welding is not much different, so It is very beneficial for shipbuilding welding.
Excellent corrosion resistance
Aluminum will form a layer of dense and strong aluminum oxide film on its surface after contacting air, which can well resist the erosion of various elements in seawater. Coupled with anodizing technology, aluminum sheets can maintain a very stable shape in seawater.
Low density
The density of aluminum is only one-third of that of iron. Under the premise of the same hull size, the industrial aluminum hull will bring lighter weight, which is greatly conducive to the improvement of the ship's speed per hour and fuel economy. With the same amount of fuel, a longer cruising range can be obtained.
Good cold and hot forming properties
Ships are subjected to cold processing (such as folding, curling, roll bending, stamping, etc.) and thermal processing (such as hot bending, pyrotechnics, etc.) during the construction process. Therefore, it is required that the marine grade aluminum alloy is easy to process and form, does not produce defects such as cracks during processing, and can still meet performance requirements such as strength and corrosion resistance after processing.
The proportion of China's shipbuilding industry in the global market is rising significantly, and China has become one of the world's important shipbuilding centers. After a round of rapid development of the shipping industry, many domestic aluminum alloy suppliers like Haomei Aluminum can provide rich marine grade aluminum alloys such as 5052 aluminum sheet metal.
