The Welding Performance of Marine Grade Aluminum 5083
In the modern shipbuilding industry, especially in the construction of high-speed ships, in order to achieve light weight and increase the speed of ships, aluminum alloy structures with lower density are often used. 5083 aluminum has high strength and strong corrosion resistance, which is suitable for the harsh marine environment and has become a commonly used marine aluminum plate.
5083 marine grade aluminum are mostly used in the tempers of H116/H321/H112, and can be used on the hulls of yachts, cruise ships, and fishing boats. The use of 5083 aluminum plate in the shipbuilding is 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.
5083 aluminum plate advantages
1. Excellent welding performance
In shipbuilding, the properties lost due to welding cannot be restored by re-heat treatment, but 5083 aluminum plate has good welding crack resistance, and the performance of welded joints after welding is not much different, so it is very suitable for shipbuilding welding.
2. Great corrosion resistance
Aluminum will form a dense aluminum oxide film on its surface after contacting air, which can well resist the erosion of various elements in seawater. Coupled with anodizing technology, the aluminum alloy plate can maintain a very stable shape in seawater.
3. Cold and hot forming properties
Ships are subjected to cold processing (such as hemming, crimping, roll bending, stamping, etc.) and thermal processing (such as hot bending) during the construction process. Therefore, it is required that the marine aluminum alloy is easy to process and form.
There are no defects such as cracks during processing, and the performance requirements such as strength and corrosion resistance can still be met after processing. The 5083 aluminum plate meets the performance requirements of marine aluminum plates.
