It features excellent weldability, corrosion resistance, and toughness, making it suitable for DIY air intake, industry fabrication, and decorative or architectural uses. The smooth, seamless interior supports consistent airflow and reduces flow resistance in piping runs. It is marketed for easy welding, stamping, and cutting to fit custom applications, enabling reliable fabrication for automotive or mechanical projects.
Key considerations:
– Dimension clarity: 38mm OD with a 32mm ID; thick wall supports higher pressure.
– Material behavior: 6061 alloy provides good formability and stability after welding.
– Project fit: Suitable for custom piping, frames, or decorative metalwork requiring durability.
Tynulox 6061 Aluminum Tubing 1.5″ OD (12″ Length)
This variant is a 1.5″ OD aluminum tube with a 12″ length and a 0.12″ (3mm) wall thickness. Like the 10″ version, it emphasizes durability, weldability, and corrosion resistance, with emphasis on smooth interior surfaces conducive to welding, stamping, and cutting for bespoke projects. It serves as a flexible component for longer piping layouts or modular designs where additional length is required without compromising structural integrity.
Allstar Performance Aluminum Round Tubing 1-1/2in x .083in x 4ft

Buying Guide: Key Purchase Considerations
Choosing the right 1.5″ aluminum tubing depends on several factors that impact performance and durability. Consider the following perspectives to compare options effectively:
- Alloy and heat treatment: 6061 alloys (T6) offer excellent weldability and strength for structural and automotive uses, while 6063 is favored for easier fabrication and good corrosion resistance in decorative or lightweight applications. Select based on duty cycle and expected loads.
- Wall thickness: Thicker walls (e.g., 0.065″ to 0.12″) increase rigidity and leak resistance, but add weight and cost. Thinner walls are easier to cut and form but may be less robust for high-pressure piping.
- Length and fit: Straight, fixed-length tubes reduce the need for joints, but you may need to cut or weld to fit custom routing. Ensure the available lengths align with your design to minimize joints and potential points of failure.
- Interior finish: Smooth interiors reduce turbulence and resistance. Brushed finishes are common for aesthetics and corrosion resistance; polished interiors may be preferred for high-flow applications in critical piping.
- Compatibility and fabrication: Check welding compatibility with your chosen welding process. Some tubes are specifically marketed for easy welding and cutting, which is advantageous for DIY builders.
- Application context: For intercooler piping, choose tubing with sufficient wall thickness to withstand pressure spikes and thermal cycling. For decorative or support applications, weight savings and ease of fabrication may take precedence.
- Availability and sourcing: Availability of standard sizes (1.5″ OD) across brands helps maintain consistency in cross-sections and performance across a project. Consider supplier reliability and return policies when sourcing multiple components.
In summary, the best choice depends on your project requirements: welding capability, required strength, length for routing, and environmental exposure. The listed options provide a spectrum from more automotive-focused piping to general-purpose aluminum tubing suited for fabrication and crafts. Always verify the exact alloy specification and wall thickness with the seller prior to purchase to ensure compatibility with your intended design.
