DESCRIPTION

A 1-1/8″ aluminum round bar 6061-T6 is a solid cylindrical rod made from 6061 aluminum alloy, with a diameter of 1-1/8 inches (1.125″). This size is typically used in applications that require a larger diameter for structural or precision-machined parts, offering strength and corrosion resistance without the weight of steel.

📐 Basic Specifications:

  • Diameter: 1-1/8 inch (1.125″ or ~28.58 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 — suitable for outdoor, marine, and industrial environments
  • Machinability: Excellent — can be easily drilled, cut, turned, and milled
  • Weldability: Excellent — works well with both MIG and TIG welding processes

🔧 Common Uses for 1-1/8″ Round Bar:

  • Shafts, spindles, and axles for larger mechanical systems
  • Pins, standoffs, and dowels
  • Heavy-duty structural rods or support beams
  • CNC machined components for custom applications
  • Tooling, fixtures, and die components
  • Automotive, aerospace, and marine applications
  • Large-scale DIY, prototyping, 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”. 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.
