Aluminium 5083 Properties

January 29, 2023

The 5083 aluminum plate belongs to the AL-Mg series alloy. Aluminium 5083 properties has high strength, especially fatigue resistance: high plasticity and corrosion resistance, and good weldability. 5083 aluminum plate is a typical representative product in the 5000 series aluminum alloys. It is a magnesium-aluminum anti-rust alloy. The state is mainly H112 and O state. It is widely used in shipbuilding and has excellent welding and corrosion resistance.

Aluminium 5083 properties

The performance of aluminium 5083 are:

1, Welding performance: 5083 aluminum plate has good welding performance and can be welded by various methods. The strength of the welded part is basically equal to the strength of the annealed state, and the extensibility and formability are good. If the temperature decreases, the tensile strength and yield strength elongation will decrease. increased, but the toughness is really good at low temperature.

2, Corrosion resistance: 5083 aluminum plate has good corrosion resistance in various states, but it is prone to stress corrosion cracking. In order to avoid this phenomenon, it is necessary to keep the working temperature of 5083 aluminum plate below 65 degrees.


The application field of 5083 aluminum plate is also very wide. On the one hand, it can be used in low temperature products, such as storage and transportation of petroleum and industrial gases, high-speed trains, pressure vessels, outer layers of ships or buildings, speedboats, etc. On the other hand, Common engineering aspects such as mechanical components, fixtures, base plates, etc.


Aluminium 5083 properties in mechanical aspect are:

Tensile strength σb (MPa): 110-136

Elongation δ10 (%): ≥20

Annealing temperature: 415°C

Yield strength σs (MPa) ≥110
