- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Weldability & Machinability
6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, delivering a strong, lightweight, and corrosion-resistant material. Produced to meet ASTM B211 standards, its T6 temper indicates it has been solution heat-treated and artificially aged to achieve optimal strength. This makes it one of the most widely used aluminum alloys for general-purpose structural and fabrication work.
As a medium-sized profile, this 1-1/2" x 3" flat bar provides substantial strength for structural bracing, machine ways, base plates, and custom machined components. Its rectangular cross-section offers a stable and easy-to-work-with foundation for drilling, tapping, milling, and welding in various industrial applications.
