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

6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, solution heat-treated and artificially aged for optimal strength. This process results in a material with a versatile combination of 45,000 PSI tensile strength, excellent weldability, and superior corrosion resistance. Conforming to ASTM B211, its flat bar form provides a stable, easy-to-work-with profile for a wide range of fabrication and structural uses.

As a medium-width bar, this 1-1/4" size is particularly well-suited for structural bracing, machine ways, wear strips, and support brackets. Its dimensions offer a good balance of strength and form factor, making it a reliable choice for equipment frames, mounting plates, and custom machined parts where both durability and light weight are required.

Specifications

  • Material: 6061-T6 Aluminum
  • Standards: ASTM B211
  • Strength/Tensile: 45,000 PSI
  • Dimensions: 1/4" Thick X 1-1/4" Wide X 144" Long
  • Finish: T6 Mill Finish
  • Certifications: Mill Test Report (MTR) Available

Applications

  • Structural Framing: Support brackets, braces, and gussets - excellent strength-to-weight ratio.
  • Machining: Base plates, fixtures, and jigs - good machinability and dimensional stability.
  • Automotive: Trailer components, running board supports, and custom brackets - lightweight and corrosion resistant.
  • Marine: Non-critical boat fittings and structural supports - resists saltwater corrosion.

Target Users

Machinists, fabricators, engineers, and maintenance teams rely on 6061-T6 aluminum flat bar for its balanced properties and versatility in construction, transportation, and industrial applications throughout the Los Angeles area.
