UNS A96061

6061 Aluminum T42 is a precipitation-hardened aluminum-magnesium-silicon alloy in a solution heat-treated and artificially aged condition, providing moderate strength with good corrosion resistance and weldability suitable for aerospace structural applications. Available in rolled, drawn, or cold-finished rod and special shapes per AMS-QQ-A-225/8, this temper balances tensile strength, yield strength, and ductility for applications requiring reliable performance at moderate temperatures.
