- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Corrosion Resistance
6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, making it one of the most versatile heat-treatable grades available. This bar complies with ASTM B211 and features a T6 temper, achieved through solution heat-treatment and artificial aging. This process yields high strength (45,000 PSI tensile), excellent corrosion resistance, and good machinability, making it a reliable choice for fabrication and structural projects.
As a large-format flat bar, this 8" x 3/8" size provides substantial surface area and structural integrity. It is an excellent choice for manufacturing heavy-duty base plates for machinery, structural support members in equipment frames, custom mounting blocks, and components for jigs and dies that require dimensional stability and strength.
