Aluminium 1100 vs 6063 – What’s the Difference

Aluminium 1100 vs 6063

When choosing the right type of aluminium for your project, there are several considerations to remember. With so many different grades and alloys available, making the right choice can be daunting. Two of the most commonly used aluminium alloys are 1100 and 6063. In this blog post, we’ll take a closer look at these two alloys, exploring their properties and applications to help you decide which is better suited for your needs.



Aluminium 1100

This alloy is known for its excellent corrosion resistance, making it a popular choice for packaging, cooking utensils, and chemical equipment applications. It is also highly ductile and has good thermal conductivity, making it suitable for various industries. Aluminium 1100 also has an excellent strength-to-weight ratio, making it ideal for lightweight structures and transportation applications. However, it does have some limitations, particularly when it comes to mechanical properties. It is not particularly strong or complex, so it may not be suitable for applications where high strength is required.

Aluminium 6063

This alloy is most commonly used in construction thanks to its excellent extrudability and anodizing properties. It is also highly corrosion-resistant and can be easily machined, making it a perfect choice for various applications. Aluminium 6063 is also easily weldable and has good mechanical properties, including high strength and hardness. However, it is essential to note that it does have a lower overall strength than some other aluminium alloys, so it may not be suitable for applications where maximum power is required.

Differences Between Aluminium 1100 and 6063


In terms of cost, Aluminium 1100 is generally less expensive than Aluminum 6063, making it a good choice for applications where cost is a primary consideration. However, it is essential to remember that the final cost of your project will depend on several factors, including the size and complexity of the parts needed and the required finishing processes.


When it comes to applications, both Aluminium 1100 and 6063 have their place. Aluminum 1100 is ideal for chemical equipment, packaging, and cooking utensils, while Aluminium 6063 is often used in construction, architectural framing, and automotive applications. Ultimately, the right choice depends on your needs and project requirements.

Other Differences

    • Aluminum 1100 is a pure aluminium alloy that contains 99.00% aluminium.
    • Aluminium 6063 is an aluminium alloy that contains 97.00% aluminium, 2.00% magnesium, and 0.50% silicon.
    • Aluminum 1100 has a higher thermal conductivity than aluminium 6063.
    • Aluminum 1100 has a lower melting point than aluminium 6063.
    • Aluminum 1100 is more ductile than aluminium 6063.




In conclusion, choosing between Aluminum 1100 and Aluminium 6063 depends on several factors, including your specific application and budget. While Aluminum 1100 offers excellent corrosion resistance and is highly ductile, it may need to be more vital for some applications. On the other hand, Aluminium 6063 is highly extrudable, corrosion-resistant, and has good mechanical properties, but there may be more cost-effective options in some cases. By considering your specific needs and consulting with a knowledgeable supplier, you can make the right choice for your particular project.
