Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

6061-T6 aluminum is a heat-treatable alloy with magnesium and silicon as its primary alloying elements, delivering good mechanical properties and excellent corrosion resistance. The T6 temper indicates it has been solution heat-treated and artificially aged to its peak strength. This grade is easily welded and machined, making it one of the most versatile aluminum alloys for fabrication and structural work.

As a large-format flat bar, this 6-inch wide by 3/8-inch thick stock is ideal for applications requiring a broad, stable surface and significant structural integrity. It is commonly used for heavy-duty base plates, support brackets for machinery, jigs and fixtures, and structural components in transportation and industrial equipment.

Specifications

  • Material: 6061-T6 Aluminum
  • Standards: ASTM B211
  • Strength/Tensile: 45,000 PSI
  • Dimensions: 6" Width x 3/8" Thickness x 144" Length
  • Finish: T6 Temper, Mill Finish
  • Certifications: MTR Available

Applications

  • Structural Engineering: Base plates for columns and machinery - its width provides a stable footprint and strength.
  • Heavy Equipment: Mounting brackets and frames - excellent strength-to-weight ratio for robust, yet lightweight assemblies.
  • Tool & Die: Jigs, fixtures, and die components - good machinability allows for precise fabrication.
  • Marine Fabrication: Deck supports and structural braces - superior corrosion resistance handles harsh environments.
