6063 Aluminum Rectangular Tubing 1in x 4in x 72in - Corrosion

Our review of the 6063 aluminum rectangular tubing focuses on buyers who need a long, clean-looking extrusion for decorative or light-structure projects. The bottom line: this tubing is best for applications where corrosion resistance and surface finish matter more than raw strength. The 1in by 4in profile with 0.125in wall and a 72in length arrives as an unpolished mill finish extrusion in T52 temper, making it a sensible choice for furniture, trim, or non-structural piping where appearance and long-term weather resistance are priorities.

Key Features

• Material: 6063 alloy offers a smoother surface and excellent corrosion resistance, which helps preserve appearance in visible installations.
• Dimensions: The 1in height, 4in width, and 0.125in wall thickness provide a stable rectangular profile suitable for light framing and trim work.
• Length: The 72in stock length reduces the need for splicing in mid-length projects and is convenient for furniture rails or decorative runs.
• Temper: T52 extruded condition balances formability and surface finish for applications where appearance is important.
• Standards: Meets ASTM B221, giving confidence that the extrusion conforms to common industry requirements for aluminum tubing.

Who It's For

This tubing is aimed at woodworkers, metal fabricators, and hobbyists who need a long, attractive aluminum profile for decorative applications such as furniture frames, trim, sign framing, or non-structural piping. Professionals doing light-duty architectural elements will appreciate the smoother mill finish and corrosion resistance.

Those who need high structural strength, heavy load-bearing members, or a polished aesthetic should look elsewhere; the 6063 alloy has relatively low strength compared with other aluminum grades and the product ships in an unpolished mill finish that may require additional surface work.

Pros & Cons

Pros

• Good corrosion resistance makes it suitable for outdoor or humid environments without heavy maintenance.
• Smoother surface than many alloys yields a cleaner look straight from the mill finish for visible installations.
• Standard 72in length and common profile dimensions reduce the need for joins in many projects.
• Conforms to ASTM B221, which supports consistent quality for sourcing.

Cons

• Edges can arrive rough and some customers report scratches or nicks from shipping, so post-delivery cleanup or deburring is often required.
• Lower strength compared with structural alloys limits use in heavy-load applications.

Our Verdict

The 6063 rectangular tubing is a practical, value-oriented choice for builders and makers who prioritize corrosion resistance and surface appearance over structural strength. It delivers a useful long length and a clean mill finish for decorative or light-duty functional work, though buyers should plan to deburr and inspect for shipping blemishes on receipt.

Frequently Asked Questions

Is this tubing suitable for outdoor use?
Yes, the 6063 alloy provides good corrosion resistance suitable for outdoor and humid environments when used in non-structural applications.

Will the tubing require finishing before installation?
Possibly; the mill finish is smooth but unpolished and some pieces may have rough edges, so light deburring or surface work may be needed for visible installations.

Can this be used for load-bearing structures?
Not recommended for heavy load-bearing uses because 6063 has lower strength than structural aluminum alloys; it is better suited for decorative or light-duty applications.
