Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, solution heat-treated and artificially aged for optimal mechanical properties. Conforming to ASTM B210, this seamless round tube offers a high strength-to-weight ratio, making it one of the most versatile aluminum alloys for structural applications. Its combination of strength, good corrosion resistance, and high weldability makes it a primary choice for fabrication projects.

As a medium-sized 1-1/4" OD tube, this product provides excellent structural integrity for resisting bending and torsion forces. It is frequently used for handrails, custom equipment frames, automotive roll cages, and marine railings where a balance of strength, weight, and durability is essential for performance and safety.

Specifications

  • Material: 6061-T6 Aluminum
  • Standards: ASTM B210
  • Strength/Tensile: 45,000 PSI
  • Dimensions: 1-1/4" OD x 0.125" Wall x 144" Length
  • Finish: T6 Temper, Mill Finish
  • Certifications: MTR Available

Applications

  • Structural: Safety railings and support columns - ideal size for handrails with excellent strength.
  • Automotive: Roll cages and chassis components - high strength-to-weight ratio for performance and safety.
  • Marine: Boat frames and tuna towers - excellent corrosion resistance in saltwater environments.
  • Industrial: Machine frames and automation robotics - good machinability and durability for equipment builds.

Target Users

Fabricators, machine shops, engineers, and automotive specialists rely on 6061-T6 Aluminum Round Tube for its strength and versatility in structural applications throughout the Los Angeles area.

Finish Options

This product comes standard with a raw mill finish. 6061 aluminum is an excellent candidate for anodizing, which creates a hard, corrosion-resistant surface. It can also be polished, brushed, or powder-coated for decorative and protective purposes. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Round tube is measured by its Outside Diameter (OD) and its Wall Thickness. Use calipers or a micrometer for an accurate reading of both dimensions.

Example: To order this round tube, specify "6061 Aluminum Round Tube, 1-1/4" OD x 0.125" Wall x 144" length".

Order Checklist

  • Product name and required dimensions (1-1/4" OD x 0.125" Wall x 144")
  • Material specification and quantity
  • Confirm grade (6061-T6) meets requirements
  • Surface finish requirements (Mill Finish)
  • Certifications required (Mill Test Report)
