- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Machinability & Weldability
6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, known for its versatile combination of high strength, good corrosion resistance, and excellent weldability. The T6 temper signifies it has been solution heat-treated and artificially aged to achieve optimal strength. It complies with ASTM B211 and is one of the most widely used aluminum alloys for general-purpose structural applications.
As a large-format bar, this 3-1/2" width is exceptionally suited for applications requiring stability and load-bearing capacity. Common uses include equipment base plates, heavy structural supports, die components, and mounting blocks where a broad, flat surface is essential for fabrication and assembly.
