- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Machinability & Weldability
6061-T6 aluminum square bar is a precipitation-hardened alloy containing magnesium and silicon, known for its high strength-to-weight ratio. It conforms to ASTM B211 and offers excellent mechanical properties, including good toughness, great weldability, and superior corrosion resistance. As a primary structural alloy, it is one of the most versatile and widely used heat-treatable aluminum grades available.
This medium 1-3/4" square profile provides dimensional accuracy and sharp corners for precise fits. It is frequently used for structural bracing, machinery jigs and base plates, transportation components, and support brackets where a balance of strength, weight, and machinability is required.
