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

6061-T6 Aluminum is a precipitation-hardened alloy containing magnesium and silicon, known for its versatile mechanical properties. The T6 temper indicates it has been solution heat-treated and artificially aged to achieve optimal strength. Compliant with ASTM B211, this flat bar provides a reliable material solution for structural and fabrication applications requiring a high strength-to-weight ratio, good machinability, and weldability.

As a medium-width bar, this 1-1/4" size is perfectly suited for structural bracing, base plates for machinery, custom brackets, and wear strips. Its rectangular profile with sharp corners is easy to drill, tap, and machine, making it a foundational component for countless industrial and commercial projects.

Specifications

  • Material: 6061-T6 Aluminum
  • Standards: ASTM B211
  • Strength/Tensile: 45,000 PSI
  • Dimensions: 1/8" Thickness x 1-1/4" Width x 144" Length
  • Finish: T6 Temper, Mill Finish
  • Certifications: Mill Test Report (MTR) Available

Applications

  • Structural Fabrication: Support braces and gussets - high strength-to-weight ratio for efficient design.
  • Machinery: Mounting plates and equipment frames - good machinability and dimensional stability.
  • Automotive: Custom brackets and chassis components - lightweight yet strong for performance applications.
  • Architectural: Trim, sills, and supports - excellent corrosion resistance for long-term durability.

Target Users

Fabricators, machinists, and engineers rely on 6061-T6 flat bar for its predictable performance and versatility in industrial, automotive, and construction projects throughout the Los Angeles area.

Finish Options

This product comes standard with a mill finish, typical of extruded aluminum products. 6061 aluminum is an excellent candidate for anodizing, which enhances corrosion resistance and allows for coloring. It can also be powder coated or polished. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Flat bar is measured by its Thickness and Width. Use calipers to measure the two perpendicular sides of the rectangular cross-section.

Example: To order this flat bar, specify "6061 Aluminum Flat Bar, 1/8 inch thick by 1-1/4 inch wide".
