6063 Aluminum Rectangular Tubing, 3/4″ x 1-1/2″, 0.125″ Wall, 36″ Length
Best for corrosion-sensitive environments where a smooth surface finish matters most. This 6063-T52 extruded tube balances moderate strength with excellent corrosion resistance and a cleaner surface compared with other alloys. The 0.125″ wall enhances stiffness for light framing without excessive weight. Ideal for enclosures, light frames, and decorative supports. Caution: Not designed for heavy structural loads where higher strength alloys would be preferred.
Blulu 6063 Aluminum Rectangular Tube
Best for projects that require a larger, stock-ready rectangular profile. The Blulu tube uses 6063 aluminum and is sold in a 1.73″ by 3″ cross-section with a 0.125″ wall and 48″ length. It’s well-suited for frames, supports, and decorative constructions where a quick-build material is valuable. This option is especially convenient for DIY enthusiasts assembling frames or light-duty structures. Caution: Verify tolerances before cutting since metric-sized outputs can drift from standard inch specifications.
Zonon 6063 Aluminum Rectangular Tubing (Two Pack)
Best for multi-project kits where you want immediate access to more material. Zonon ships in a two-pack of 2″ x 4″ cross-section with a 0.125″ wall and 12″ length. The 6063 alloy provides good corrosion resistance and workable machining. This size is convenient for prototyping frames, guard rails, or small enclosures. Caution: The shorter length may require joining for longer spans, which adds assembly considerations.
OnlineMetals 6063 Rectangular Tubing, 1″ x 2″
Best for versatile light framing and equipment supports. This 1″ x 2″ tube with a 0.065″ wall offers a lightweight yet stiff profile and good machinability. It’s well-suited for framing enclosures, hobbyist builds, and automotive or electronics projects. Caution: The thinner wall means working with high-torque fasteners or bending operations should be done with care to avoid deformation.
Kwweeoo Rectangular Tubing (Two Pack)
Best for value-conscious buyers needing more than one tube. This 1″ x 2″ tube with a 0.08″ wall is offered as a two-pack with a 39.37″ length. The data indicates a strong aluminum alloy (notably 6061 in the description), providing a robust strength-to-weight ratio and good corrosion resistance for brackets, shelves, frames, and decorative applications. Caution: Verify alloy details if exact 6063 specification is required for a project.
Buying Guide: Key Purchase Considerations
- Strength vs. weight: For structural frames, choose thicker walls (0.125″ or more) and larger cross-sections when load matters. For decorative or light-duty frames, lighter walls (0.065″–0.08″) may suffice.
- Alloy and temper: 6063-T52 is commonly used for its corrosion resistance and good machinability. Consider temper if you require specific strength or ductility for bending and forming.
- Dimensions and tolerances: Metric-to-inch conversions can cause small dimensional differences. Always measure the precise cross-section and confirm compatibility with existing connectors or profiles.
- Length requirements: Longer lengths reduce joints but may require specialty cutting tools. Shorter lengths improve handling but necessitate more joints for larger frames.
- Corrosion resistance: For outdoor or humid environments, prioritize aluminum grades with excellent corrosion resistance and smooth surfaces to resist grime buildup.
- Compatibility with hardware: Verify hole patterns, internal channels, or surface finishing requirements to ensure fasteners and brackets fit properly.
Frequently Asked Questions
- What is metric aluminum rectangular tubing best used for?
It’s ideal for light to moderate framing, furniture frames, machine guards, and DIY projects where corrosion resistance and light weight are important.
- How do I choose wall thickness?
Thicker walls provide more stiffness and load-bearing capacity; thinner walls save weight and material cost but may flex under higher loads.
- Is 6063 T5/T52 preferred for most DIY projects?
6063-T52 is common for its combination of corrosion resistance and workability, making it suitable for many verticals from enclosures to frames.
- Can metric tubing be cut and welded easily?
6063 aluminum welds well with proper technique, and cutting is straightforward with standard metalworking tools, but check tolerances and avoid gouging the surface.
- What should I watch out for when ordering online?
Confirm exact cross-section, wall thickness, and length. Double-check tolerances and verify that the alloy matches your project requirements.
These five options cover common project needs from small DIY builds to light industrial framing. The selections emphasize corrosion resistance, workable machinability, and convenient lengths, helping buyers pair the right profile with their application. Whether you’re assembling a guard, a frame, or a decorative structure, metric aluminum rectangular tubing provides a versatile, dependable solution.
