DESCRIPTION

A 1-3/4″ aluminum round bar 6061-T6 is a solid cylindrical rod made from 6061 aluminum alloy, with a diameter of 1-3/4 inches (1.750″). This size is commonly used for heavy-duty structural, mechanical, and custom-machined parts where a high level of strength and durability is required, while still maintaining the lightweight and corrosion-resistant benefits of aluminum.

📐 Basic Specifications:

  • Diameter: 1-3/4 inches (1.750″ or ~44.45 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 — ideal for outdoor, marine, and industrial environments
  • Machinability: Very good — easy to drill, mill, cut, and turn
  • Weldability: Excellent — well-suited for both MIG and TIG welding processes

🔧 Common Uses for 1-3/4″ Round Bar:

  • Shafts, spindles, and axles for larger and heavy-duty machinery
  • Pins, standoffs, and dowels
  • Large structural rods or support beams for mechanical assemblies
  • Custom machined parts for high-stress applications
  • Tooling, fixtures, and die components
  • Automotive, aerospace, and marine applications
  • Heavy-duty DIY projects, large-scale prototypes, 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.
