- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Weldability & Corrosion Resistance
6061-T6 is a precipitation-hardened aluminum alloy containing magnesium and silicon, known for its excellent mechanical properties and weldability. Conforming to ASTM B211 standards, this square bar provides high strength, good toughness, and great workability. The T6 temper indicates it has been solution heat-treated and artificially aged to achieve its maximum strength, making it a reliable structural material.
As a large-profile bar, this 2-1/4" square is ideal for heavy structural applications where strength and weight savings are critical. Common use cases include machinery base plates, heavy equipment mounting, support brackets, and large fixtures requiring dimensional stability and robust performance.
