Aluminium 2007 vs 6082 – What’s the Difference

Aluminium 2007 vs 6082

Every metal has unique properties, making it more suitable for specific uses than its counterparts. Aluminium is no different. Many different types of aluminium, each with different properties, are available in the market. This makes it important to know which type of aluminium to choose for specific applications. Among the various types of aluminium available in the market, the most commonly used are 2007 and 6082. This blog post will explore the differences between Aluminium 2007 and 6082 and which is better suited for which purposes.

Difference Between Aluminium 2007 and 6082


The composition of the two aluminium alloys is the primary factor that differentiates them from each other. 2007 aluminium has a composition of 0.2 per cent copper, 0.7 per cent magnesium, 1.3 per cent lead, and 0.6 per cent iron. In contrast, 6082 aluminium comprises 0.6 per cent silicon, 0.9 per cent magnesium, 1 per cent manganese, and 0.6 per cent iron.


2007 aluminium is renowned for its high strength, even at high temperatures. This makes it suitable for use in applications that require good mechanical properties. On the other hand, 6082 aluminium has a lower yield strength than its counterpart. However, it has better corrosion resistance and is more suitable for applications that require good wear and tear resistance.


Both Aluminium 2007 and 6082 are very machinable. But in terms of machinability, Aluminium 6082 is the clear winner. Adding silicon to 6082 makes it easier to machine, with less chance of chips and burrs forming. This makes 6082 a better choice for manufacturing applications that require high-speed machining.


Weldability is another essential factor when choosing between 2007 and 6082 aluminium. Aluminium 2007 is much easier to weld than 6082 because of its lower copper content. However, when heat treated, welding can be compromised. 6082 aluminium can be welded using standard techniques, but specific welding techniques are recommended to prevent cracking.


Because of its higher yield strength and good mechanical properties, 2007 aluminium is typically used in applications that require strength and durability. Examples of such applications include the aerospace and transportation industries. As for 6082 aluminium, it is popularly used in applications that require excellent corrosion resistance and machinability. This makes it suitable for manufacturing applications and use in marine environments.


In conclusion, the differences between Aluminium 2007 and 6082 are numerous. They each have unique properties that make them better suited to specific applications. When purchasing aluminium, knowing what properties you need for your application is important, and then choosing the appropriate alloy. With this knowledge, you can choose between Aluminium 2007 and 6082, depending on your requirements.
