- 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 as its primary alloying elements. The T6 temper signifies it has been solution heat-treated and artificially aged to achieve its optimal strength. Conforming to ASTM B211, it provides a versatile combination of high strength, good workability, and excellent corrosion resistance, making it one of the most widely used aluminum alloys.
As a large-format flat bar, this 4-inch width provides substantial surface area and rigidity. It is ideal for fabricating robust structural components, machinery base plates, mounting blocks, heavy-duty brackets, and support braces where strength and dimensional stability are critical requirements.
