- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Weldability & Corrosion Resistance
6061-T6 aluminum is a precipitation-hardened alloy with magnesium and silicon as its primary alloying elements. Conforming to ASTM B211, it is solution heat-treated and artificially aged to achieve optimal strength, excellent corrosion resistance, and good machinability. Its combination of properties makes it one of the most widely used aluminum alloys for general-purpose structural and fabrication applications.
As a medium-width bar, this 3" x 3/8" size is a standard choice for structural bracing, support brackets, mounting plates, and machine ways. Its flat, rectangular profile is easy to drill, mill, and weld, making it a fundamental building block for custom equipment and vehicle frames.
