- 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, delivering a versatile combination of strength, corrosion resistance, and workability. The T6 temper signifies it has been solution heat-treated and artificially aged to achieve its optimal mechanical properties, including 45,000 PSI tensile strength. This grade conforms to ASTM B211 and is one of the most widely used alloys for structural applications.
As a medium-width bar, this 2-1/2" x 3/8" size is an excellent choice for structural bracing, machine ways, wear strips, and support members. Its rectangular profile provides a stable, flat surface for drilling, tapping, and mounting, making it a foundational component for general fabrication, machinery, and transportation equipment where moderate strength and light weight are required.
