Yongsheng marine 5083 aluminum sheet


People’s research on the performance of aluminum alloys originated in the early part of this century. In the 1940s, it was found that adding magnesium and silicon to aluminum alloys could effectively resist seawater corrosion. 5083 aluminum alloy is the most common aluminum alloy grade in shipbuilding. 1954 It was included in the official aluminum alloy grade in 2010, so 5083 aluminum alloy is also called marine aluminum alloy. At the same time, this alloy is also widely used in other industrial fields.

The advantages of 5083 aluminum sheet applied in the shipbuilding field lie in its high strength, corrosion resistance, plasticity and excellent welding performance. In the 1960s, with the advancement of science and technology, the production costs of aluminum sheets and strips gradually decreased, and they were widely used as lightweight materials. They were used to make yacht shells, hull superstructures, masts, and port infrastructure. building. In the 1970s, high-speed aluminum passenger ships first appeared in Scandinavia. With their advantages of speed and economy, aluminum ships once became a model in the field of passenger ships.

5083 aluminum sheet

The 5383 aluminum sheet is an upgraded version of the 5083. The former has better corrosion resistance than the latter, and its hardness has also increased by 10%. These potential performance improvements reduce the number of welding ships. The yield point of the welded structure was increased by 15%. With the characteristics of formability, weldability and yield, 5383 and 5083 aluminum sheets are also favored by large high-speed ship manufacturers.

The aluminum industry’s 5083 aluminum sheet and 5383 aluminum sheet are the main products in the field of marine aluminum sheet, and both occupy an important position in shipbuilding.
