- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Weldability & Corrosion Resistance
6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, known for its versatile combination of high strength, good workability, and excellent corrosion resistance. Conforming to ASTM B211, its T6 temper indicates it has been solution heat-treated and artificially aged to achieve optimal mechanical properties. This makes it a foundational material for general-purpose structural and fabrication projects.
As a large-format bar, this 4-1/2" x 2-1/2" size provides substantial cross-sectional strength for demanding loads. It is frequently used for machinery base plates, heavy structural supports, die components, and robust framing where light weight and corrosion resistance are also critical.
