- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Corrosion Resistance
6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, known for its versatile mechanical properties. Produced to meet ASTM B211 standards, it has a T6 temper, indicating it has been solution heat-treated and artificially aged to achieve optimal strength. This process results in excellent weldability, good machinability, and superior corrosion resistance, making it a go-to for general fabrication.
As a large-format flat bar, this 3-1/4" x 2-1/4" size is specified for applications demanding rigidity and strength. It is commonly used for heavy equipment base plates, structural framing members in machinery and transportation, support braces, and large machined fixtures.
