What Is 5083 Grade Aluminium

2024-06-05

5083 grade aluminium is a commonly used aluminum alloy material, belonging to the 5000 series aluminum alloy. It is mainly composed of aluminum (Al) and magnesium (Mg), while containing a small amount of manganese (Mn) and chromium (Cr). Aluminium grade 5083 is a high magnesium alloy, with excellent corrosion resistance, high strength and good welding performance, is a commonly used in marine engineering and shipbuilding aluminum alloy materials.

5083 grade aluminium has good seawater corrosion resistance, can be used in the marine environment for a long time without easy to be corroded. At the same time, 5083 aluminium grade alloy also has high tensile strength and bending strength, suitable for the manufacture of hulls, plates, cabin structures and other components. In addition, 5083 grade aluminum alloy also has good processing performance and can be deep-drawn, welded, cut and other processing techniques. These properties of 5083 aluminium plate make it an indispensable material in many industries, especially where high strength, good corrosion resistance and weldability are required.

Chemical composition of 5083 grade aluminium:
Aluminum (Al): remainder
Silicon (Si): ≤0.40
Copper (Cu): ≤ 0.10
Magnesium (Mg): 4.0 ~ 4.9
Zinc (Zn): ≤ 0.25
Manganese (Mn): 0.40 ~ 1.0
Titanium (Ti): ≤0.15
Chromium (Cr): 0.05～0.25
Iron (Fe): 0.000 ~ 0.400 (individual elements ≤ 0.05, total ≤ 0.15)

Mechanical properties of 5083 grade aluminium:
Tensile strength (σb): ≥270 MPa
Conditional yield strength (σ0.2): ≥110 MPa

Main Properties of 5083 grade aluminium:
Good corrosion resistance, especially suitable for low load parts working in liquid or gaseous media.
Excellent weldability, good cold workability and medium strength.
Beautiful surface after anodizing treatment, good arc welding performance.

Application scope of 5083 grade aluminium:
5083 aluminum alloy is widely used in marine, aerospace and automotive applications.
Specifically used in the manufacture of aircraft fuel tanks, fuel lines, and sheet metal parts for transportation vehicles and ships.
Also used in the manufacture of instrumentation, street lamp brackets and rivets, hardware products, electrical enclosures.
In the need for strict fire protection pressure vessels (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration devices, television towers, drilling equipment, transportation equipment, missile parts, armor, etc. also have applications.

Overall, 5083 grade aluminium has a wide range of applications in the field of marine engineering and shipbuilding, and is an aluminum alloy material with excellent performance.
