- 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, offering a versatile combination of high strength, workability, and corrosion resistance. The T6 temper signifies it has been solution heat-treated and artificially aged to achieve its optimal mechanical properties. Conforming to ASTM B211, its rectangular profile with sharp corners is a foundational material for countless structural and fabrication applications requiring a lightweight, strong, and reliable component.
As a medium-sized flat bar, the 1-3/4" width is perfectly suited for structural bracing, support members, machine ways, and wear strips. Its dimensions provide substantial rigidity for framework and base plates without adding excessive weight, making it a go-to choice for custom machinery, vehicle chassis components, and architectural supports.
