DESCRIPTION

A 2-3/4″ aluminum round bar 6061-T6 is a solid cylindrical rod made from 6061 aluminum alloy, with a diameter of 2-3/4 inches (2.750″). This size is typically used for large, heavy-duty structural, mechanical, and custom-machined parts where superior strength, durability, and resistance to corrosion are required. The aluminum alloy provides excellent strength-to-weight ratio, making it ideal for high-demand applications.

📐 Basic Specifications:

  • Diameter: 2-3/4 inches (2.750″ or ~69.85 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 — highly resistant to corrosion, making it ideal for marine, outdoor, and industrial environments
  • Machinability: Excellent — can be easily drilled, cut, milled, and turned
  • Weldability: Excellent — works well with both MIG and TIG welding

🔧 Common Uses for 2-3/4″ Round Bar:

  • Shafts, spindles, and axles for heavy-duty machinery and large-scale systems
  • Pins, standoffs, and dowels for large mechanical assemblies
  • Heavy-duty structural rods or support beams
  • Custom machined parts for high-stress or critical applications
  • Tooling, fixtures, and die components
  • Automotive, aerospace, and marine applications
  • Large-scale DIY projects, 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”. This does NOT apply to Cut To Size items. Those will be +.125″, -0.00″ tolerances.
