⚙️ Material – 6061-T6 Aluminum

6061-T6 is a heat-treated aluminum alloy known for its strength and versatility. The T6 temper indicates that the material has been solution heat-treated and artificially aged.​

Key Properties:

  • Corrosion Resistance: Excellent, making it suitable for marine and outdoor applications.
  • Machinability: Good, allowing for precise fabrication.
  • Weldability: Excellent, compatible with various welding methods.
  • Formability: Good, suitable for bending and forming processes.​

🧪 Mechanical Properties ( for 6061-T6)

  • Tensile Strength: Approximately 45,000 psi
  • Yield Strength: Approximately 40,000 psi
  • Elongation at Break: Minimum 17%
  • Hardness: Brinell 95
  • Density: Approximately 0.0975 lb/in

🌡️ Thermal Conductivity

  • Thermal Conductivity: Approximately 167 W/m·K​

This high thermal conductivity makes 6061-T6 aluminum suitable for applications requiring efficient heat dissipation.​

* 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”. Since we cut the material specifically for your order, they follow these tolerances: Length: +0.125″ / -0.062” – Please note that during cutting, the blade removes about 1/16″ of material (kerf). This is a normal part of the process and is already considered within the stated tolerances.
