Aluminium 6082 vs 2014 – What’s the Difference

Aluminium 6082 vs 2014

Aluminium has become an essential metal for various industries due to its unique properties, such as lightweight, high strength, corrosion resistance and ease of fabrication. Many alloys, including Aluminium 6082 and 2014, are widely used for different purposes. But what are the differences between them? This blog post will explore the technical and practical differences between Aluminium 6082 and 2014.

Difference Between Aluminium 6082 and 2014


Aluminium 6082 and 2014’s chemical composition differs significantly, affecting their physical and mechanical properties. Aluminium 6082 primarily consists of Aluminium, silicon, magnesium, and manganese. The presence of magnesium and silicon enhances its strength and corrosion resistance significantly. In contrast, Aluminium 2014 contains copper as a primary alloying element, which gives it high strength and excellent machinability.

Strength and Hardness:

The strength and hardness of Aluminium 6082 are higher than those of 2014 alloys. Aluminium 6082’s ultimate strength is 310 MPa, and its yield strength is 240 MPa, while 2014’s ultimate strength is 470 MPa, and its yield strength is 400 MPa. However, 2014 has lower ductility when compared to 6082, making it unsuitable for high-forming applications.


Aluminium 6082 is widely used to fabricate structural parts for aircraft, ships, railway vehicles, high-speed trains, and machinery due to its excellent strength and corrosion resistance. In contrast, Aluminium 2014 is frequently used as a structural material in aerospace applications, including aircraft wings, fuselages and other critical components.

Machinability and Weldability:

Since Aluminium 2014 contains copper as a primary alloying element, it has excellent machinability, making it the preferred material for critical aircraft components. On the other hand, Aluminium 6082 has less machinability, but it is still considered to have good machinability. Aluminium 6082 has excellent weldability, making it a preferred choice for welded fabrications in aerospace and other applications.

Corrosion Resistance:

Aluminium 6082 has good resistance to seawater, making it an ideal material for marine applications. In contrast, Aluminium 2014 has moderate corrosion resistance and is susceptible to stress corrosion cracking.


In conclusion, Aluminium 6082 and 2014 are highly sought-after alloys with unique properties that make them suitable for different applications. Aluminium 6082 has high strength, good corrosion resistance, and excellent weldability, making it preferred for aerospace and structural applications. Aluminium 2014, on the other hand, is preferred for its high strength, excellent machinability, and suitability for aerospace applications. Therefore, when choosing between Aluminium 6082 and 2014, it is necessary to consider their composition, strength, hardness, application, machinability, weldability, and corrosion resistance to ensure the best material for your project.
