Aluminium 6060 vs 5083 – What’s the Difference

Aluminium 6060 vs 5083

Aluminium is a versatile and widely used metal favoured for its strength, lightweight properties, and natural corrosion resistance. Two of the most popular alloys in the market are 6060 and 5083. Although they have similarities, these two types of aluminium have different properties, making them suitable for different applications. In this article, we will explore the differences between aluminium 6060 and 5083 to help you decide when selecting the right alloy for your project.

What is Aluminium 6060?

Let us start by looking at Aluminium 6060. This is a medium-strength alloy with excellent mechanical properties and good corrosion resistance, which makes it ideal for use in the construction of light-duty structures such as fencing, window frames, and furniture. Aluminium 6060 also has a good appearance, making it suitable for decorative applications. It can be easily machined, welded, and shaped using common processing techniques without losing its toughness.

What is Aluminium 5083?

On the other hand, Aluminium 5083 is a high-strength alloy that offers excellent corrosion resistance and is commonly used in marine and industrial applications. It boasts a high level of resistance to saltwater corrosion and is, therefore, ideal for use in shipbuilding and other offshore structures. Aluminium 5083 is also resistant to mechanical wear and tear, making it suitable for manufacturing parts subject to frequent use and handling. It should be noted, however, that Aluminium 5083 may not be suitable for decorative applications as it has a dull appearance.

Difference Between Aluminium 6060 and 5083

One of the key differences between Aluminium 6060 and 5083 is their chemical composition. Aluminium 6060 has silicon, magnesium, and manganese as major alloying elements. On the other hand, Aluminium 5083 has magnesium and small amounts of chromium and manganese as its major alloying elements—this difference in composition results in different mechanical and corrosion-resistant properties.

Another difference lies in their machinability. While both alloys are easily machined, Aluminium 5083 is more challenging to process than Aluminium 6060. This is due to its higher strength and hardness, which means that it requires more cutting force and compression to the machine.


One of the primary differences between aluminium 6060 and 5083 is their composition. As mentioned above, aluminium 6060 contains 97.5% aluminium, 2.5% magnesium, and 0.5% silicon. On the other hand, aluminium 5083 contains 95.5% aluminium, 4% magnesium, and 0.5% manganese. The different composition of these two alloys gives them different properties and makes them suitable for different applications.


Another difference between aluminium 6060 and 5083 is their strength. Aluminium 6060 is considered to be a medium-strength alloy, while aluminium 5083 is considered to be a high-strength alloy. This difference in strength is due to the different composition of these two alloys; aluminium 6060 contains more silicon than aluminium 5083, which makes it stronger but less corrosion-resistant.

Corrosion Resistance

As mentioned above, one of the key benefits of aluminium 5083 is its high corrosion resistance. This property makes aluminium 5083 ideal for use in maritime and aerospace applications where parts are exposed to salt water or high levels of stress respectively


In conclusion, the choice between Aluminium 6060 and 5083 depends on the specific application and the desired properties of the final product. If you need an alloy with good strength and corrosion resistance for light-duty structures and decorative applications, Aluminium 6060 may be the best choice. On the other hand, if you require a high-strength alloy with excellent corrosion resistance for demanding marine and industrial applications, Aluminium 5083 is the way to go. Regardless of your choice, working with a reputable supplier who can provide high-quality products that meet your specifications is important.
