5383 Marine Aluminum Plate

The advantages of 5383 aluminum alloy high strength, good corrosion resistance, high thermal conductivity, high conductivity, and good weldability, etc., have been widely used in the ship's field field.

The 5xxx aluminum alloys are commonly used in aluminum alloy 5083, 5456, 5A01, etc. On the basis of 5083, 5383 alloys are developed by adding trace CU, Zn and a small amount of ZR. The strength, corrosion and welding performance of the 5383 alloy are higher than 5083, and the development and production of 5383 alloys will gradually meet the requirements of my country on the upper layer of the ship's ship. Establishing environmental application provides new materials.

5383 Marine Aluminum Plate vs 5083 Marine Aluminum Plate

5383 Marine Aluminum Plate is an upgraded version of 5083 Marine Aluminum Plate.

  • 5383 Marine Aluminum Plate strong corrosion resistance and increased hardness by 10%.
  • The yield point of the welding structure increased by 15%.

High corrosion 5383 aluminum plates are mainly used for construction of ships and petroleum drilling platforms around salt water. It can still maintain strength under extremely cold conditions, so it is also used to make low -temperature pressure vessels and storage tanks.

Chemical composition of 5383 grade aluminium

The MG content in the 5383 aluminum alloy is between 4.0 and 5.2 %. In the corrosive environment, such as in the environment, it is prone to corrosion failure. Therefore, the 5383 plate needs to be stabilized to improve its corrosion resistance.
