Aluminium 2007 vs 6061 – What’s the Difference

Aluminium 2007 vs 6061

Aluminium is a versatile metal that’s used in a wide range of industries. But not all aluminium is created equal. In this blog post, we will compare two popular aluminium grades: 2007 and 6061. We’ll examine their differences, explore their properties, and highlight their advantages and disadvantages. Whether you’re a contractor, fabricator or an interested reader, you’ll find this information valuable.

Difference Between Aluminium 2007 and 6061


One of the main differences between Aluminium 2007 and 6061 is their composition. Aluminium 6061 is an alloy that’s made up of magnesium, silicon, copper, and zinc. It’s a heat-treatable alloy with good formability and weldability. Aluminium 2007, on the other hand, is an aluminium-copper alloy with excellent mechanical properties and high strength-to-weight ratio. It’s commonly used in the aerospace and transportation industries.

Mechanical Properties:

Aluminium 6061 is a versatile alloy that can be used for numerous applications. It has good machinability and is an excellent choice for structural, machine, and automotive components. It has a yield strength of around 35,000 psi and a tensile strength of around 45,000 psi. Aluminium 2007, on the other hand, has a yield strength of around 64,000 psi and a tensile strength of 72,000 psi. This makes it an excellent choice for high-stress applications.

Corrosion Resistance:

Aluminium 2007 and 6061 have good corrosion resistance, making them suitable for outdoor applications. However, Aluminium 6061 has better corrosion resistance than aluminium 2007. This is due to the alloy’s magnesium and silicon, which help prevent the formation of rust and other types of corrosion. This makes it a better choice for marine applications or areas with high humidity.


Aluminium 6061 is a highly weldable alloy that can be easily welded using all the common welding techniques. Additionally, it can be joined using a wide range of processes, including TIG, MIG, and Stick welding. Aluminium 2007, on the other hand, is a bit harder to weld due to its high copper content. However, it can be successfully welded using TIG or MIG welding with the right technique and filler material.


Finally, the cost of Aluminium 6061 and 2007 can vary depending on the supplier, the size of the order, and the market demand. However, in general, Aluminium 6061 is more affordable than Aluminium 2007. This is because Aluminium 6061 is a more commonly used alloy with a wider range of applications.


In conclusion, Aluminium 2007 and 6061 have advantages and disadvantages. The choice between the two will depend on the specific application, cost, and the desired mechanical properties. Working with a reputable supplier is important to ensure that you get the right type of aluminium for your project. By understanding the differences between the two types of aluminium, you can make an informed decision that will lead to a successful project.
