DESCRIPTION

A 4″ aluminum round bar 6061-T6 is a solid cylindrical rod made from 6061 aluminum alloy, with a diameter of 4 inches (4.000″). This size is often used for large structural, mechanical, and custom-machined parts that require significant strength, high durability, and resistance to corrosion, while benefiting from the lightweight properties of aluminum.

📐 Basic Specifications:

  • Diameter: 4 inches (4.000″ or ~101.60 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, milled, cut, and turned
  • Weldability: Excellent — well-suited for MIG and TIG welding

🔧 Common Uses for 4″ Round Bar:

  • Shafts, spindles, and axles for large, heavy-duty machinery and mechanical systems
  • Pins, standoffs, and dowels for heavy-duty applications
  • Heavy-duty structural rods or support beams for industrial, aerospace, or construction projects
  • Custom machined parts for high-stress mechanical assemblies
  • 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.
