- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Corrosion Resistance
6061-T6 is a precipitation-hardened aluminum alloy containing magnesium and silicon, making it one of the most versatile heat-treatable structural alloys. Produced to meet ASTM B211 standards, it provides an excellent strength-to-weight ratio, superior corrosion resistance, and good machinability. Its T6 temper indicates it has been solution heat-treated and artificially aged to achieve its optimal strength properties, making it a reliable choice for demanding applications.
As a medium-sized profile, this 1-1/4" square bar is perfectly suited for structural applications like equipment framing, support brackets, and braces. Its dimensional stability and strength also make it a primary material for machined parts, including jigs, fixtures, base plates, and various industrial components where both light weight and durability are required.
