- 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, offering a versatile combination of high strength, weldability, and corrosion resistance. The T6 temper indicates it has been solution heat-treated and artificially aged for optimal strength. Conforming to ASTM B211, its flat bar form provides a solid rectangular cross-section for general-purpose structural and fabrication applications.
As a large-format bar, this 4" width provides substantial surface area and structural integrity. It is an excellent choice for fabricating machinery base plates, heavy structural supports, die components, and mounting blocks that require superior dimensional stability and strength without the weight of steel.
