5083 aluminum plate, 5383 aluminum plate for marine use

People's research on the properties of aluminum alloys originated in the early part of this century. In the 1940s, it was found that the addition of magnesium and silicon to aluminum alloys can effectively resist seawater corrosion. The 5083 aluminum alloy is the most common aluminum alloy grade in the shipbuilding process, 1954. It was incorporated into the official aluminum alloy grade in the year, so the 5083 aluminum alloy is also called marine aluminum alloy. At the same time, the alloy is also widely used in other industrial fields.

The advantages of 5083 aluminum sheet in the marine field are its high strength, corrosion resistance, plasticity and excellent welding performance. In the 1960s, with the advancement of technology and progress, the production costs of aluminum sheets, aluminum strips, etc. were gradually reduced. They were used as lightweight materials. They were used to make yacht shells, hull superstructures, masts and port foundations. Facilities construction. In the 1970s, high-speed aluminum passenger ships first appeared in Scandinavia. With its speed and economic advantages, aluminum ships once became a model in the passenger ship field.

The 5383 aluminum plate is an upgraded version of the 5083. The former is highly resistant to corrosion and the hardness is increased by 10%. These potential performance improvements reduce the number of welding vessels. The yield point of the welded structure increased by 15%. Due to its shape, weldability and yield characteristics, the 5383 and 5083 aluminum sheets are similar to those of large high-speed ship manufacturers.
Chalco Aluminum's 5083 aluminum plate and 5383 aluminum plate are the main products in the field of marine aluminum plate, and occupy an important position in shipbuilding. As the research progresses, it is believed that in the near future scientists will develop lighter, harder aluminum alloy sheets for shipbuilders to create a new generation of aluminum vessels.
