- 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 outstanding mechanical properties and workability. The T6 temper indicates it has been solution heat-treated and artificially aged to achieve optimal strength. This material meets ASTM B211 standards, making it a reliable choice for demanding structural applications where a lightweight yet strong material is essential.
As a large-format flat bar, this 12-inch wide profile is exceptionally suited for applications requiring broad, stable surfaces. Its dimensions make it ideal for heavy equipment base plates, structural support members, large jigs and fixtures, and robust mounting brackets that demand dimensional stability and strength.
