5083 Aluminum Coil For Boat DNV

5083 aluminum coil for boat dnv has low density, non-magnetic and good low temperature performance. Using it as the structural material of the ship can reduce the weight of the ship, increase the load capacity, and improve the stability and speed. Therefore, for all kinds of small and medium-sized ships, especially hydrofoils, hovercraft, and small military ships, it is a development direction to choose 5083 aluminum for boat as the shell material. The application of aluminum alloy in ship construction has been developed from the initial superstructure to the all-welded aluminum structure ship, but no matter which part of the ship is applied, it is inseparable from the welding between aluminum alloys and between aluminum alloys and steel structures. And different welding methods can get different welding effects.

5000 series (A1-Mg series) non-heat-treated alloys, such as 5052, 5083 and other high-Mg alloys, have appropriate mechanical strength and fatigue strength, and are excellent in corrosion resistance, weldability and workability. 5083 aluminum coil for boat dnv for corrosion-resistant weldable structures are being widely used in marine and other fields. 6000 series alloys are mostly used as extrusion profiles due to their excellent extrusion properties and corrosion resistance.

The Al-Mg-based alloy is a non-heat-treated strengthened alloy in which Mg is added to aluminum alone or Mg and Mn are added simultaneously. Alloys such as 5052 and 5083 containing 2.5% to 5% Mg can have a tensile strength of 196 to 294 MPa with different Mg content, and can be used as welding structural materials. When combined with an additive metal of appropriate composition, the weldability is very good, and the corrosion resistance, especially seawater corrosion resistance is also very good. However, when the Mg content is greater than 5%, the alloy is prone to stress corrosion. Therefore, the method of adding Mn or Cr is usually used to prevent this corrosion phenomenon. Alloy aluminum sheet for boat with different properties can be obtained by cold work hardening. In order to prevent the alloy from aging softening at room temperature, stabilization treatment is also required.

In foreign countries, 5083 aluminum coil for boat dnv have long been widely used in ships and civilian ships. The construction of aluminum alloy welded ships and aluminum superstructures will surely promote the development of my country's naval equipment and water transportation.
