DESCRIPTION

A 1-3/8″ aluminum round bar 6061-T6 is a solid cylindrical rod made from 6061 aluminum alloy, with a diameter of 1-3/8 inches (1.375″). This size is typically used for applications that require more substantial strength and durability while keeping the material lightweight and corrosion-resistant, making it ideal for both structural and custom-machined parts.

📐 Basic Specifications:

  • Diameter: 1-3/8 inches (1.375″ or ~34.93 mm)
  • Material: Aluminum Alloy 6061
  • Temper: T6 (solution heat-treated and artificially aged)
  • Shape: Solid round bar (not hollow)

🧪 6061-T6 Aluminum Properties:

  • Tensile Strength: ~45,000 psi
  • Yield Strength: ~40,000 psi
  • Hardness: Brinell ~95
  • Corrosion Resistance: Excellent — ideal for outdoor, marine, and industrial environments
  • Machinability: High — easily cut, drilled, turned, and milled
  • Weldability: Excellent — great for MIG and TIG welding

🔧 Common Uses for 1-3/8″ Round Bar:

  • Shafts, spindles, and axles for larger machinery and heavy-duty applications
  • Pins, standoffs, and dowels
  • Heavy-duty structural rods or support beams
  • Custom machined components in mechanical assemblies
  • Tooling, fixtures, and die components
  • Automotive, aerospace, and marine applications
  • Larger DIY projects, prototypes, and industrial fabrication

* Prices subject to change without notice due to the Metals Market fluctuations.
* All ‘value length’ and ‘value pack’ item measurements are subject to a “mill tolerance”. A product may be produced several thousandths of an inch, either over or under the stated thickness, and still be within “mill tolerance”. This does NOT apply to Cut To Size items. Those will be +.125″, -0.00″ tolerances.
