OnlineMetals Aluminum 6063-T52 Square Tubing
Product Type: Aluminum square tubing for structural framing. The OnlineMetals tube is manufactured from 6063-T52 alloy, known for a favorable strength-to-weight ratio and good corrosion resistance. This 2″ x 2″ cross-section with a 1/8″ wall thickness is suitable for lightweight frames, machine guards, and architectural framing. The tube ships with a mill finish, ensuring clean, straight cuts and minimal prep before fabrication. Its versatility makes it a common choice for DIY framing projects and professional construction alike.
Key considerations include alloy compatibility for welding and machining, precise length tolerance, and surface finish. While 6063-T52 offers good corrosion resistance, environments with heavy exposure to moisture or chemicals may require protective coatings. The 36″ length provides a practical stock size for modular builds and can be cut to fit custom dimensions. For assembly, users typically rely on standard fasteners, corner brackets, and stock connectors compatible with 2″ profiles.
Gisafai Aluminum Square Tubing 1″ x 24″
Product Highlights: This 1″ x 1″ square tube measures 24″ long with a 0.12″ wall thickness, crafted from 6061 aluminum for strength and corrosion resistance. The kit includes two pieces, making it suitable for quick customizations or modular frame projects. The 6061 alloy is well-regarded for its machinability and structural performance, ideal for DIY projects, equipment housings, or lightweight frames. The 24″ length supports small assemblies or can be joined for longer spans with proper end treatments.
Considerations involve weldability and compatibility with your fabrication tools. The 0.12″ wall provides a balance between rigidity and weight, but if a heavier-duty frame is needed, look for thicker walls or larger cross-sections. The AISI 6061 aluminum offers good corrosion resistance and finishes well, which is beneficial for exposed outdoor installations or splash-prone environments.
Evecad 1″ x 1″ x 48″ Aluminum Tube
Evecad offers a 1″ x 1″ square aluminum tube with a 1/8″ wall thickness, extending to 48″ in length. Constructed from high-quality 6063-T6 aluminum, the tube emphasizes strength and corrosion resistance, reducing the risk of cracking over time. The natural mill finish simplifies machining, drilling, and welding for DIY projects, furniture framing, or home improvement tasks. The long 48″ length supports extended frames or can be cut into shorter segments as needed.
Potential trade-offs include transport weight and the need for precise end-cuts to maintain square geometry. Aluminum’s non-magnetic nature means it can be easier to work with when drilling or tapping, but slower cutting and more wear on certain tooling may occur compared to steel. Evaluation should include load requirements and environmental exposure to ensure longevity.
80/20 1″ x 1″ Structural Aluminum Tube
This 1″ x 1″ structural aluminum tube from 80/20 is designed for modular framing systems. With a 1/8″ wall thickness and a 24″ length, it is well-suited for building lightweight frames, machine enclosures, and adjustable supports. The alloy is typically 6063-T6, offering good corrosion resistance and excellent machinability. The Mississippi-based framing systems are popular for custom builds, allowing designers to assemble robust structures with standard connectors.
Key considerations include compatibility with 80/20 accessories, ease of cutting and joining, and how the 24″ length integrates with existing projects. For larger projects, users often combine multiple tubes with corner brackets or compatible connectors to build stronger frames. Surface finishing options like anodizing or powder coating can improve outdoor durability.
Allstar Performance Alum Square Tubing 3/4″ x 3/4″
Allstar Performance offers a compact aluminum square tube with 3/4″ x 3/4″ cross-section, extending 7.5 feet in length. This option is ideal for lightweight chassis framing, brackets, or display frames where smaller profiles are preferred. The tubing is aluminum, providing corrosion resistance and a favorable strength-to-weight ratio, though it may not support heavy structural loads like larger sections.
Practical considerations include the balance between rigidity and weight, especially in mobile or portable installations. The 7.5-foot length can be cut and joined with standard fasteners for modular assemblies. Finishing options, including protective coatings, can extend life in outdoor or humid environments.
Buying Guide: Key Purchase Considerations And Comparisons
Material and alloy choice: The majority of aluminum square tubing used in structural and DIY projects relies on 6063-T6/T52 alloys for strength, machinability, and corrosion resistance. 6061 is also common, offering good strength and weldability. Check alloy designation to ensure compatibility with your fabrication methods (welding, drilling, tapping).
Wall thickness and cross-section: A thicker wall increases rigidity and load-bearing capability but adds weight. For most hobbyist projects, 1/8″ walls provide a good balance between strength and ease of handling for 1″ and 2″ cross-sections. Larger frames may require thicker walls or larger cross-sections.
Length and cutability: Applications vary from short segments to long runs. Look for lengths that minimize waste and reduce the need for excessive cutting. Consider whether you need pre-cut pieces or raw tubes that you will cut to size on-site.
Finish and corrosion resistance: Mill finishes are common, but painting, powder coating, or anodizing can dramatically extend outdoor lifespan. If the project is exposed to moisture or corrosive environments, maintenance planning is important.
Compatibility with accessories: Modular framing systems (like 80/20) rely on compatible connectors and brackets. If you plan to expand later, verify that tube sections and fittings align with available accessories to avoid compatibility gaps.
Machinability and fabrication: Aluminum is easier to machine than many metals but may wear out standard tooling faster than steel in some cases. Drill bits and saw blades suitable for aluminum reduce surface damage and ensure cleaner cuts. Pre-machined corners or factory-burnished edges can save time.
Cost and availability: Aluminum tubes vary in price by alloy, length, and finish. For ongoing projects, consider bulk purchases or supplier relationships to ensure consistent stock and finish quality across all sections.
Applications overview: Use cases range from furniture framing and DIY projects to machinery guards and architectural framing. When selecting a tube, align the cross-section, wall thickness, and alloy with the intended load, exposure, and manufacturing method to achieve reliable performance.
