Before you select an aluminum pipe for your project, you should ask yourself a few important questions. These questions help you match the right alloy to your needs and avoid costly mistakes.
What is the main purpose of the pipe?
Decide if you need the pipe for structural support, decorative features, or custom extrusions. 6061 works best for strength and load-bearing. 6063 is ideal for smooth finishes and complex shapes.
Will the pipe be exposed to outdoor or corrosive environments?
If your project faces rain, humidity, or chemicals, 6063 offers better corrosion resistance. For indoor or less harsh settings, 6061 provides reliable protection.
Do you need to machine, weld, or form the pipe?
6061 machines well and handles heavy-duty tasks. 6063 forms easily and welds with less effort, making it great for custom profiles.
Is appearance or surface finish important?
Choose 6063 if you want a shiny, smooth look. 6061 gives a good finish but may need extra polishing or anodizing.
What are the load and strength requirements?
For heavy loads or structural frames, 6061’s higher strength is the right choice. For lighter, non-structural uses, 6063 is often enough.
What is your budget and timeline?
6063 usually costs less and is easier to source for standard shapes. 6061 may cost more but delivers higher performance for demanding jobs.
Tip: Answering these questions helps you narrow down your options and choose the best pipe for your application.
You can use a checklist to make your decision easier. This checklist links each factor to the technical performance of 6061 and 6063 aluminum pipes. Review each point and check off the features that matter most for your project.
| Selection Factor | 6061 Aluminum Pipe | 6063 Aluminum Pipe |

| Hardness | Higher hardness; resists dents and wear | Softer; easier to form and shape |
| Extrudability | Good; suitable for simple shapes | Excellent; ideal for complex and custom profiles |
| Formability | Moderate; less flexible | Excellent; bends and forms easily |
| Heat Treatability | Heat-treatable; can increase strength | Not heat-treatable; strength remains constant |
| Corrosion Resistance | Good; suitable for most environments | Excellent; preferred for outdoor and marine use |
| Weldability | Weldable; requires more care | Easier to weld; less risk of cracking |
| Surface Finish | Good; may need extra finishing | Superior; smooth and shiny right after extrusion |
| Typical Applications | Structural frames, machinery, automotive, aerospace | Architectural, decorative, electrical, piping |
You can see how each technical metric supports your choice. For example, if you need a pipe for a machine frame or a heavy-duty support, 6061’s strength and hardness make it the best fit. If you want a custom-shaped railing or a decorative trim, 6063’s extrudability and finish stand out.
Note: Lansi Aluminum offers both 6061 and 6063 pipes in a wide range of profiles, including T slot, curved, and custom extrusions.
Many people make mistakes when choosing aluminum pipes. You can avoid these pitfalls by learning from industry experience and technical studies.
Many designers pick the strongest alloy without checking if it is weldable. Some strong alloys do not weld well, which can cause failures.
Some users forget that the modulus of elasticity, not just strength, controls how much a pipe bends. This can lead to unexpected deflection in frames or supports.
Weldability differences between alloys often get overlooked. 6061 welds well but needs careful technique. 6063 welds more easily and with less risk.
The heat-affected zone (HAZ) in welds can lose strength. Many people do not account for this, which can weaken the final structure.
Post-weld heat treatment can restore strength in 6061, but it is not practical for large assemblies.
Some users ignore the need for the right filler metal when welding. This can cause cracks or weak joints.
Many people do not consider the environment. Using a pipe with lower corrosion resistance outdoors can lead to early failure.
Some projects use aluminum pipe where high heat is present. Aluminum’s lower melting point makes it less suitable for these jobs compared to steel or copper.
⚠️ Always match the alloy to your application, not just the highest strength or lowest price. Review your project’s needs and check the technical data before you buy.
By asking the right questions, using a clear checklist, and avoiding common mistakes, you can choose the best aluminum pipe for your project. Lansi Aluminum’s wide selection and expert support make it easy to find the right solution for automation, construction, or custom design needs.
