6061-T6 is a precipitation-hardened aluminum-magnesium-silicon alloy in a solution heat-treated and artificially aged condition, providing tensile yield strength around 40 ksi with good corrosion resistance and machinability. Widely used in aerospace, automotive, and structural applications where moderate strength, weldability, and environmental resistance are required, particularly in forgings, extrusions, and drawn shapes.
