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

6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, delivering high strength, good toughness, and excellent corrosion resistance. Produced to meet ASTM B211 standards, its T6 temper indicates it has been solution heat-treated and artificially aged to achieve its optimal strength characteristics. This combination makes it one of the most versatile heat-treatable alloys for general-purpose fabrication and machining.

As a small-profile bar, this 3/8" square size is perfect for lightweight structural applications and precision components. It is frequently used for custom brackets, mounting blocks, jigs, fixtures, and decorative trim where sharp corners and dimensional accuracy are critical for fit and function.

Specifications

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

Applications

  • Machinery: Jigs, fixtures, and small base plates - good machinability and stability.
  • Structural: Lightweight support brackets, gussets, and braces - high strength-to-weight ratio.
  • Electronics: Mounting frames and standoffs - good thermal conductivity and easy to machine.
  • Architectural: Trim, accents, and custom framework - excellent surface for finishing.

Target Users

Machinists, fabricators, and engineers rely on 6061-T6 Aluminum Square Bar for its predictable performance and versatility in manufacturing and construction projects throughout the Los Angeles area.

Finish Options

This product comes standard with a mill finish, which is a smooth, unpolished surface suitable for most industrial applications. 6061 aluminum responds exceptionally well to finishing. For specific project requirements, it can be anodized for enhanced corrosion and wear resistance, or powder-coated for color. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Square bar is measured by the width of one of its flat sides. This product has two equal sides of 3/8 inch. Use calipers for an accurate measurement.

Example: To order this square bar, specify "6061 Aluminum Square Bar, 3/8 inch, by 144 inch length".
