- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Corrosion Resistance
6061-T6 aluminum is a precipitation-hardened alloy that offers a versatile combination of high strength, good corrosion resistance, and excellent weldability. This heat-treatable grade has been solution heat-treated and artificially aged to achieve its optimal strength properties, conforming to ASTM B211. It is one of the most widely used aluminum alloys for general-purpose structural and fabrication applications due to its reliable performance.
The large 2" x 3-1/2" cross-section of this bar provides exceptional strength and rigidity, making it ideal for heavy-duty structural members, equipment base plates, support brackets for machinery, and large-format machined components that require dimensional stability and a high strength-to-weight ratio.
