- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Machinability & Weldability
6061-T6 is a precipitation-hardened aluminum alloy containing magnesium and silicon, which gives it excellent mechanical properties and weldability. It conforms to ASTM B211 and is known as a versatile structural alloy. The T6 temper indicates it has been solution heat-treated and artificially aged to achieve its maximum strength of 45,000 PSI, making it a reliable choice for demanding applications.
As a medium-sized profile, the 1-1/8" square bar is perfectly suited for structural frames, support brackets, machine jigs, fixtures, and base plates where substantial strength is needed without the bulk of larger profiles. Its dimensional accuracy is critical for precision assemblies.
