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

6061-T6 is a precipitation-hardened aluminum alloy containing magnesium and silicon, known for its excellent mechanical properties and weldability. It is heat-treated to a T6 temper for optimal strength. This material conforms to ASTM B211 and combines a high strength-to-weight ratio with superior corrosion resistance, making it one of the most widely used aluminum grades for general-purpose fabrication and structural applications.

As a large-format flat bar, this 6-inch wide profile is ideal for applications requiring substantial surface area and structural integrity. Common uses include heavy equipment base plates, mounting brackets for machinery, structural framing supports, and components for jigs, fixtures, and dies where a strong, stable, and lightweight material is required.

Specifications

  • Material: 6061-T6 Aluminum
  • Standards: ASTM B211
  • Strength/Tensile: 45,000 PSI
  • Dimensions: 1/4" Thickness x 6" Width x 144" Length
  • Finish: T6 Temper Mill Finish
  • Certifications: Mill Test Report (MTR) Available

Applications

  • Machinery & Automation: Base plates for motors and equipment - the wide profile provides a stable, machinable mounting surface.
  • Structural Engineering: Gussets and support braces - offers high strength-to-weight ratio for reinforcing frames and chassis.
  • Marine Fabrication: Structural components and brackets - excellent corrosion resistance in marine environments.
  • Transportation: Trailer and truck body components - lightweight strength reduces overall vehicle weight without compromising durability.
