- 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, delivering high strength, good workability, and excellent corrosion resistance. This T6 temper condition means it has been solution heat-treated and artificially aged for maximum strength. Conforming to ASTM B211, it is a versatile, lightweight alternative to steel for structural and general fabrication projects.
This medium-width 1-3/4" flat bar is an ideal choice for structural bracing, machine ways, wear strips, and mounting plates. Its rectangular profile and consistent dimensions simplify fabrication, drilling, and tapping for custom components in machinery, transportation, and architectural projects where strength and stability are required.
