DESCRIPTION

A 1-1/4″ aluminum round bar 6061-T6 is a solid cylindrical rod made from 6061 aluminum alloy, with a diameter of 1-1/4 inches (1.250″). This size is commonly used in applications that require a substantial amount of strength while still maintaining the lightweight advantages of aluminum. It is widely used in structural, mechanical, and fabrication applications.

📐 Basic Specifications:

  • Diameter: 1-1/4 inches (1.250″ or ~31.75 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 — great for outdoor, marine, and industrial environments
  • Machinability: Very good — can be easily drilled, milled, turned, and cut
  • Weldability: Excellent for MIG and TIG welding

🔧 Common Uses for 1-1/4″ Round Bar:

  • Shafts, spindles, and axles for heavy-duty machinery
  • Pins, standoffs, and dowels
  • Large structural rods or support beams
  • Custom machined parts for mechanical assemblies
  • Tooling, fixtures, and die components
  • Automotive, aerospace, and marine applications
  • DIY projects, hobby work, and prototyping where extra strength is needed
* 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”. Since we cut the material specifically for your order, they follow these tolerances: Length: +0.125″ / -0.062” – Please note that during cutting, the blade removes about 1/16″ of material (kerf). This is a normal part of the process and is already considered within the stated tolerances.
