- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Machinability & Corrosion Resistance
6061-T6 aluminum round bar is a versatile, heat-treatable alloy containing magnesium and silicon. The T6 temper indicates it has been solution heat-treated and artificially aged to achieve its optimal strength properties. This process results in a material with an excellent strength-to-weight ratio, superior corrosion resistance, and good workability. It meets ASTM B211 standards for rolled or cold-finished bar.
As a large-diameter bar, this 4-1/2" round is ideal for robust applications requiring significant strength and substance. Common uses include heavy-duty shafts, large-scale machined components, structural supports, rollers, and forging stock for creating custom, high-strength parts.
