6063 Aluminum Rectangular Tubing, T52, 3/4″ x 1-1/2″
Best for cost-conscious framing and lightweight structures. This tube offers good corrosion resistance with a smooth surface finish, making it suitable for aesthetic frames and basic DIY builds. The 0.75″ x 1.5″ profile and 0.125″ wall provide a modest stiffness for simple projects like light-duty racks or enclosures. Caution: lower strength compared to thicker-walled options means avoid heavy-duty loads.
Blulu 6063 Rectangular Tube, 1.73″ x 3″
Best for larger frames and decorative DIY projects. The 1.73″ x 3″ cross-section yields a higher moment of inertia, which helps resist bending in wider structures such as furniture frames or display stands. It’s manufactured from 6063 aluminum, offering corrosion resistance and decent machinability. Caution: larger size may require more robust joining methods and longer fabrication times.
OnlineMetals 6063 Rectangular Tubing, 1″ x 2″
Best for versatile framing and DIY fabrication. Its 1″ x 2″ footprint with a thin 0.065″ wall delivers a balance of light weight and rigidity. The 6063-T52 alloy provides good corrosion resistance and a smooth extrusion finish, aiding precise machining and clean finishes. Choose this for machine guards, lightweight enclosures, or custom furniture frames. Limitation: thinner walls may limit load-bearing capacity under high stress.
1/8″ Wall x 1-1/2″ x 3″ Aluminum Rectangle Tube, 6061-T6
Best for projects requiring higher strength-to-weight ratio. This 6061-T6 alloy offers stronger mechanical properties than typical 6063 tubes, suitable for structural frames and brackets that demand more rigidity. The 1.5″ x 3″ cross-section with a 0.125″ wall provides a solid rectangular profile. Caution: weight and cost may be higher, and welding should follow 6061 guidelines.
Kwweeoo Aluminum Rectangular Tubing, 2 Pack
Best for multi-piece projects and ongoing fabrication needs. The two-pack format provides ready-to-use stock for side rails, frames, or shelving supports, with a 1″ x 2″ cross-section and 0.08″ wall thickness. The alloy is 6061, offering strong performance and good welding characteristics. Caution: only available in the listed length—custom cuts may incur additional processing steps.
Buying Guide: Key Purchase Considerations
- What load will the tubing support? For light framing and decorative use, thinner walls are acceptable. For structural frames, prefer thicker walls or higher-strength alloys such as 6061-T6.
- Are corrosion resistance and surface finish important? 6063-T52 tubes offer easier machining and smoother finishes, ideal for visible frames. If weldability and strength are priority, 6061-T6 is a solid choice.
- What size profile fits your design? Narrow profiles excel in compact builds; larger cross-sections provide stiffness but increase weight and cost.
- How will you join sections? Consider tabs for welding, gussets, or mechanical fasteners. Some tubes accept standard brackets; others may require specialty connectors.
- What length and quantity are needed? Stock tubes often come in standard lengths; plan for extra length to accommodate cuts and waste.
- What finish is desired? Anodizing may enhance appearance and corrosion resistance for aluminum frames used outdoors or in display applications.
FAQ
- What is the difference between 6063 and 6061 aluminum tubes?
6063-T52 focuses on corrosion resistance and a smooth surface; 6061-T6 emphasizes higher strength and weldability for structural uses. - Is a thinner wall okay for DIY projects?
Yes for light loads, display frames, or non-structural supports. For heavier loads, choose thicker walls or higher-strength alloys. - Can these tubes be cut easily?
Yes, many are designed for machinability; ensure proper saws and protective PPE to achieve clean cuts and accurate lengths. - Are the tubes suitable for outdoor use?
6063 alloys offer good corrosion resistance, making them suitable for outdoor frames with appropriate finishes or coatings. - What joining methods are recommended?
Welding is common for 6061; for 6063, mechanical fasteners or brackets are often used to avoid surface finish damage. - Do these tubes come in standard lengths?
Most listings show common stock lengths; additional cuts may be required to fit your project dimensions.
