The broad range of aluminum alloys in the market today can make your selection process challenging. Nevertheless, understanding the varying forms and your application process requirements can be a kick off for finding an optimum extruded aluminum alloy.

 

This write up provides an in-depth comparison of two of the most common alloys so you make the best pick for your project. Comparing the performance characteristics of the 6061 and 6063 aluminum can help you examine distinct properties with regard to your application needs. Read on!

Comparing 6061 vs 6061 Aluminum Extrusions: Comparison

Although the 6063 and 6061 aluminum alloys share some properties, each entails a specialized extrusion process. The maximum stress load for 6061 aluminum is 290 Mpa / 42,060 psi while the 6063 option has a sufficient tensile strength of 186/26,977 psi.

 

When it comes to corrosion resistance, the 6061 aluminum has a fair corrosion resistance which further improves when oxidizing begins. This can be attributed to the presence of chromium, which enhances the passivity of aluminum.

The 6063 has outstanding corrosion protection as it allows for effortless anodization. The 6063 has enhanced workability because of its softer chemical make-up. The workability of 6061 aluminum is less than that of the 6063 aluminum but is still ideal for CNC uses. Another crucial consideration worth a mention is that both the 6061 and 6063 aluminum alloys can be difficult to anneal while forming intricate dimensions because they are heat treatable.

 

6061 vs 6063 Aluminum: Application by Form

Round Tube

The round tube is lightweight, hollow and corrosion resistant making it ideal for a variety of structural and architectural uses. The 6061-aluminum hollow form is strong and commonly used in structural framework, protection, and sleeve coupling.

 

6063 aluminum has high strength and hence has common uses like piping, furniture work, handrail systems, and industrial engineering.

 

Square Tube

6061 aluminum square tubes have beneficial properties like medium-high strength, corrosion resistance and excellent weldability hence the common uses ranging from structural and machine parts, to fixtures and recreational equipment.

On the other hand, the 6063 has superior strength-to-weight ratio and smooth finish characteristics making it suitable for a wide range of construction uses like machine components, racks, frames, and automobiles.

 

Bar

The 6061 bar has proven popularity in fabrication processes in the medical, aerospace, and transportation industries. This can be attributed to its outstanding corrosion resistance, good machinability, and good workability.

 

A 6063 bar works great as a substitute for the 6061 bar. It is visually appealing with a fine finish. You can use it for lightweight applications with corrosion resistance requirements.

 

Angles

The 6061 and 6063 aluminum angles allow for enhanced strength in structural and architectural applications. The radius corners of the 6061 alloy provide superior strength in framework, braces, structural support and aerospace components.

 

The sharp inside radius of the and quality finish of the 6063 makes it useful in architectural projects that prioritize visual appeal in comparison to strength.

 

Channels

A common feature evident in both the angles and channels is the inside radius corners. You can use 6061 aluminum channels in applications that require superior strength like trailers, truck beds and braces. The 6061 are ideal for visually appealing frameworks and structural support.

 

Should You Choose Aluminum Alloy 6061 or 6063?

There are different forming processes used in the production of the 6061 and 6063 extruded alloys. More often than not, the end products have satisfying properties for diverse applications. That said, you can use your application needs as a key guideline while choosing between 6061 and 6063 aluminum alloys.

Interestingly both the 6061 and 6063 aluminum can fit a single application. In such cases, ensure you go with the one that offers the most benefits for your project.

 

What Are 6061 & 6063 Aluminum Alloyed With?

6061 and 6063 can be alloyed to enhance their mechanical properties and allow high tempering. They share alloying elements however; the quantities of iron, chromium, silicon, and copper in 6061 aluminum are nearly double the amount in the 6063 aluminum.

 

Conclusion

Understanding the difference between the characteristics of the 6061 and 6063 aluminum can be crucial to the success of your architectural or structural project.

 

The 6061 aluminum is the right choice for high strength structural applications while the 6063 aluminum can help you achieve aesthetically pleasing architectural components.

 

Selecting the correct alloy requires a comprehensive understanding of their properties and potential uses. A clear comprehension of these alloys of the 6xxx series can help professionals save on cost while achieving optimum performance in their projects.
