Price range: $14.00 through $51.99

Part#: ARO61118 Category
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 are subject to change without notice due to fluctuations in the metals market. | All “Value Length” and “Value Pack” item measurements are subject to standard mill tolerances. | Products may be manufactured several thousandths of an inch over or under the stated dimensions and still be within acceptable mill tolerances. All bar, tube, structural, pipe, sheet, plate, and similar products sold on our website are custom cut to the lengths and sizes selected by the customer at the time of purchase. These are not stocked as pre-cut items. Because each order is cut specifically to customer specifications, all cut materials are considered custom products and are not eligible for cancellation, return, or exchange once production has begun. Our standard cutting tolerances are:

  • Length: +0.125″ / -0.062″
  • During the cutting process, the saw blade removes approximately 1/16″ (kerf) of material. This is a normal part of the manufacturing process and is already included within the stated cutting tolerances.
