Aluminium 2618 vs 6061

When choosing the right aluminium alloy for your project, you may face a tough decision between two of the most popular alloys: 2618 and 6061. Both alloys have unique properties and advantages, but which is the best choice for your application? In this blog post, we’ll look at the differences between aluminium 2618 and 6061 to help you make an informed decision.

What is Aluminium 2618?

Aluminium 2618 is an aluminium alloy developed specifically for use in the aerospace industry. It is one of the strongest aluminium alloys, with a yield strength of over 700 MPa. Additionally, it has excellent weldability and resistance to corrosion.

What is Aluminium 6061?

Aluminium 6061 is widely used in various industries due to its high strength-to-weight ratio and good weldability. Additionally, it has excellent corrosion resistance and can be easily anodized to create various colours.

Difference Between Aluminium 2618 and 6061


When comparing the two alloys, it is clear that each has its advantages and disadvantages. Aluminium 2618 is stronger than 6061 but is not as easily welded. Additionally, 6061 is more resistant to corrosion than 2618. However, both alloys are lightweight and have a high strength-to-weight ratio.


Aluminium 2618 is typically used in applications where strength is paramount, such as aerospace. Additionally, it is often used in racing applications due to its high strength. On the other hand, Aluminium 6061 is more commonly used in general engineering applications as it is easier to weld and more corrosion-resistant. It is also often used in the construction industry for various applications.


Aluminium 2618 is typically more expensive than 6061 due to its higher strength and better weldability. However, the price difference between the two alloys will vary depending on the market conditions at purchase.


When it comes to choosing between aluminium 2618 and 6061, it ultimately comes down to the specific needs of your project. If you need high-strength properties and can afford the higher cost and more specialized fabrication processes, aluminium 2618 may be the better choice. However, if you need a versatile and cost-effective alloy with good corrosion resistance, aluminium 6061 may be the way to go. Whatever your choice, work with a reputable supplier who can provide high-quality aluminium products and expert guidance.
