6061 Aluminum Pipe Schedule 40 5 in Nominal - Durable Extruded Tube

Our review of the 6061 Aluminum Pipe, Schedule 40, finds it best suited for projects that need a strong but lightweight structural tube. The single biggest reason to buy is the combination of 6061-T6 strength and machinability, which makes this 24 in length pipe easy to cut, weld, and finish for applications from mounting hardware to custom structural parts. The pipe's consistency and compliance with ASTM-B249 give confidence that it will fit into professional fabrication and hobby builds alike.

Key Features

• Material: 6061-T6 aluminum offers an excellent strength-to-weight ratio, making the pipe sturdy without adding excessive mass.
• Dimensions: The 5.047 in inside diameter and 5.563 in outside diameter provide predictable clearance for spacers, couplings, or inserts.
• Wall Thickness: A 0.258 in wall gives the pipe good rigidity for structural and mechanical uses while remaining workable.
• Length and Finish: Supplied in a 24 in extruded length that is convenient for cutting to size and welding into assemblies.
• Standards: Meets ASTM-B249 which assures consistency for professional and industrial applications.

Who It's For

The pipe is ideal for fabricators, machinists, and hobbyists who need a reliable tubing option for aerospace, automotive, marine, or structural projects where corrosion resistance and weldability matter. It also suits those making mounts, couplings, or custom parts such as spacers and camera rig components.

Those who should look elsewhere include users needing very long continuous lengths beyond 24 in or those requiring non-standard alloys or thinner walls for weight-critical, high-performance racing builds where a different grade or manufacturing process might be preferred.

Pros & Cons

Pros

• Good strength-to-weight performance from 6061-T6, making it versatile for structural and mechanical use.
• Above-average corrosion resistance that fits marine and outdoor applications.
• Customers report solid material quality and value for money, and functionality for tasks like mounting a weather station.

Cons

• Limited to a 24 in supplied length, so multiple pieces or joints are needed for longer runs.
• Size perceptions are mixed among buyers, so confirm exact dimensions for tight-fit applications.

Specifications

Our Verdict

This 6061 Aluminum Pipe is a practical choice for anyone needing a short extruded tube with good weldability, corrosion resistance, and predictable dimensions. For common workshop and light industrial uses it represents solid value, especially when cutting, fitting, or machining is planned.

Frequently Asked Questions

Is this pipe weldable?
Yes. 6061-T6 is known for good weldability and is suitable for typical shop welding processes.

Can it be machined to tight tolerances?
Yes. The alloy and extruded form offer good machinability for cutting, drilling, and finishing to size.

Is the length fixed at 24 in?
Yes. The supplied length is 24 in; order multiple lengths if longer sections are required.
