Aluminum alloy used in ships has many benefits
1. Excellent welding performance. Welding has more obvious advantages than riveting, because in shipbuilding, the performance lost by welding cannot be restored by reheating. Aluminum alloy has good welding crack resistance, and the performance of welded joints after welding is not much different, so it is very Conducive to shipbuilding welding.
2. Excellent corrosion resistance. Aluminum will form a dense and strong aluminum oxide film on its surface when exposed to air, which can well resist the erosion of various elements in seawater. Coupled with anodizing technology, aluminum alloy can maintain a very stable shape in seawater.
3. Low density and lightness. The density of aluminum is only equivalent to one-third of that of iron. Under the premise of the same hull size, the aluminum alloy hull will bring lighter weight, which is greatly beneficial to the high speed and fuel economy of the ship. Obtain a longer cruising range under the measurement.
