DESCRIPTION

An aluminum flat bar 2-1/2 x 4 6061-T6

📐 Dimensions:

  • Thickness: 2-1/2 inches (2.500″)
  • Width: 4 inches (4.000″)

🧪 Material: 6061-T6 Aluminum

  • 6061: A heat-treatable aluminum alloy that contains magnesium and silicon, offering:
    • High strength-to-weight ratio
    • Excellent corrosion resistance, particularly in marine, outdoor, and industrial environments
    • Good weldability and machinability
  • T6 Temper: This means the aluminum is heat-treated and artificially aged, resulting in maximum strength, hardness, and stability.

⚙️ Typical Mechanical Properties:

  • Tensile Strength: ~45,000 psi
  • Yield Strength: ~40,000 psi
  • Brinell Hardness: ~95
  • Density: 0.098 lb/in³

🧰 Common Applications:

  • Structural beams, framing, and supports
  • Machine bases, custom mounting plates, and brackets
  • Aerospace, automotive, and marine components
  • Heavy-duty industrial tooling and fabrication
  • Custom high-strength parts for demanding environments

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.
