6063 Aluminum Tubing, 3/4″ x 1-1/2″ (36″ Length)
This 6063 aluminum rectangular tubing offers corrosion resistance and a smooth surface finish, making it suitable for lightweight frames and decorative frameworks. The 0.125″ wall thickness provides a balance between rigidity and ease of handling. With a 36″ length, it is ideal for small to medium-sized DIY projects, furniture frames, and hobbyist builds that require a non-magnetic, corrosion-resistant option. The T52 temper provides good strength while maintaining formability for fabrication.
Blulu 6063 Rectangular Tube, 1.73″ x 3″ (48″ Length)
Constructed from 6063 aluminum, this rectangular tube emphasizes corrosion resistance and durability for longer-lasting assemblies. The larger cross-section (1.73″ x 3″) offers increased rigidity for frames and supports, while the 0.125″ wall thickness keeps weight manageable. The 48″ length is convenient for longer spans or pieces that will be cut to size. Ideal for DIY projects, frames, showcases, and lightweight structural components in moderate-load applications.
OnlineMetals 6063 Rectangular Tubing, 2″ x 3″ (24″ Length)
This 6063 aluminum rectangular tubing with a 2″ x 3″ cross-section provides a higher moment of inertia compared to smaller profiles, enhancing stiffness for frames and structural assemblies. The 0.125″ wall thickness keeps the piece light while maintaining reasonable torsional strength. The T52 temper adds a modest strength boost over annealed variants, making it suitable for lightweight enclosures, racks, and hobbyist machinery frames.
OnlineMetals 6063 Rectangular Tubing, 0.75″ x 1.5″ (24″ Length)
A compact option in the 0.75″ x 1.5″ family, this 6063 rectangular tubing is well-suited for small frames, brackets, and light-duty assemblies. The 0.125″ wall thickness provides a balance between rigidity and weight, while the T52 temper improves strength and dent resistance. Useful for models, display stands, and light structural components in be-spoke or modular projects.
Zonon 6063 Rectangular Tubing, 2″ x 4″ (12″ Length)
This Zonon rectangular tubing delivers a larger cross-section for projects requiring more rigidity and support while maintaining a thin wall at 0.125″. The 12″ length is suitable for shorter spans, custom brackets, and frame components in DIY construction and industrial projects. Made from 6063 aluminum, it benefits from corrosion resistance and good workability for cutting, drilling, and milling.
Buying Guide: Key Considerations For Thin Wall Aluminum Tubing
Choosing the right thin wall aluminum rectangular tubing involves balancing strength, weight, and cost. Here are some essential considerations to guide your selection:
- Alloy and temper: 6063 is common for its corrosion resistance and smooth surface, with T52 temper offering higher strength. 6061 provides good strength but different properties; confirm alloy and temper for your load requirements.
- Wall thickness and cross-section: A 0.125″ wall is standard for many lightweight frames. Thinner walls reduce weight but can limit load-bearing capacity; larger cross-sections can improve rigidity without increasing wall thickness.
- Dimensions tolerances: Check height and width tolerances, especially if you’re building precise frames or assemblies. Some suppliers note metric-origin tolerances that may affect fitment.
- Length options: Short lengths (12″–36″) are convenient for modular builds, while longer pieces reduce joints. Consider how you will cut and join segments (screws, brackets, welding, or adhesive methods).
- Finishes and surface: A smooth, corrosion-resistant surface reduces friction, improves appearance, and eases fabrication. Anodizing or painting can add protective layers and color options.
- Availability and sourcing: Online retailers often stock a range of cross-sections. Availability can influence lead time and cost, especially for larger or uncommon profiles.
- Applications and load expectations: For hobby frames, light aerospace models, or display stands, 6063 with a T52 temper is typically adequate. For higher load applications, consider thicker walls or reinforced designs.
- Machinability: Aluminum, particularly 6063, generally machines well with standard tools. Be mindful of wall thickness relative to drill bit size and step drilling to avoid deformation.
In summary, the best thin wall aluminum rectangular tubing depends on the required cross-section, length, and environmental exposure. Aluminum’s natural corrosion resistance makes these profiles suitable for indoor and sheltered outdoor projects, while careful sizing ensures adequate stiffness without unnecessary weight.
