DESCRIPTION

A 3″ aluminum round bar 6061-T6 is a solid cylindrical rod made from 6061 aluminum alloy, with a diameter of 3 inches (3.000″). This size is commonly used for large structural, mechanical, and custom-machined components that require substantial strength, durability, and resistance to corrosion, while still benefiting from the lightweight properties of aluminum.

šŸ“ Basic Specifications:

  • Diameter: 3 inches (3.000″ or ~76.20 mm)
  • Material: Aluminum Alloy 6061
  • Temper: T6 (solution heat-treated and artificially aged)
  • Shape: Solid round bar (not hollow)

šŸ§Ŗ 6061-T6 Aluminum Properties:

  • Tensile Strength: ~45,000 psi
  • Yield Strength: ~40,000 psi
  • Hardness: Brinell ~95
  • Corrosion Resistance: Excellent ā€” highly resistant to corrosion, making it ideal for marine, outdoor, and industrial environments
  • Machinability: Excellent ā€” can be easily drilled, cut, milled, and turned
  • Weldability: Excellent ā€” works well with MIG and TIG welding

šŸ”§ Common Uses for 3″ Round Bar:

  • Shafts, spindles, and axles for heavy-duty machinery and mechanical 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

A product may be produced up to several thousandths of an inch over or under the stated thickness and still be within ā€œmill toleranceā€.

This does NOT apply to Cut To Size items. Those will be +.125ā€, -0.00ā€ tolerances.

*Ā 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.Ā 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.
