With the pursuit of wealth and the thirst for gold, Europeans opened new shipping routes at the end of the 15th century. Since then, the process of human civilization has developed by leaps and bounds. The opening of new shipping routes has made more and more countries realize the importance of marine resources, and to this day, various countries are still competing for the status of "maritime supremacy". In the process of moving towards deep blue, the importance of ships is self-evident, so the question is, what material is more suitable for shipbuilding?
From prehistoric times to the use of wood as boats, for a long period of time, humans have made wooden boats propelled by human or wind power. In 1879, the world's first steel ship came out, and since then ships have entered the era of steel ships. In recent years, under the call of energy conservation and emission reduction, ship lightweight has also begun to be put on the agenda, and lightweight and corrosion-resistant marine aluminum plates have entered the public's field of vision.
Generally, marine aluminum plates need to have high specific strength and specific modulus, that is, medium strength, corrosion resistance and weldability. At the same time, it is also necessary to have outstanding cold and hot forming functions, because the ship production is subject to cold working and hot processing a variety of treatments, so marine aluminum alloy must be easy to process and form, no cracks, and after processing can still meet the strength and corrosion resistance requirements. In view of the need to meet the above requirements, 5083 aluminum plate, 5086 aluminum plate, 5754 aluminum plate, etc. stand out among many aluminum plates because of their excellent performance, and the commonly used marine aluminum plates on the market are also these alloys.
