- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Machinability & Corrosion Resistance
6061-T6 is a precipitation-hardened aluminum alloy containing magnesium and silicon, solution heat-treated and artificially aged for high strength. This process results in excellent corrosion resistance and weldability, making it one of the most widely used grades. It meets ASTM B211 standards and provides a reliable, consistent material for demanding fabrication and machining projects.
The large 3-1/4" diameter classifies this bar for heavy-duty applications. It is an excellent choice for manufacturing industrial rollers, large hydraulic manifolds, forging stock for custom parts, and robust structural supports where both strength and low weight are critical.
