6061 Aluminum T4
VerifiedmetalUNS A96061
6061-T4 is a precipitation-hardenable aluminum alloy (Al-Mg-Si system) in solution heat-treated and naturally aged condition, offering moderate strength with good corrosion resistance and weldability for aerospace structures, aircraft components, and general engineering applications. The T4 temper provides lower strength than T6 but superior ductility and machinability, making it suitable for applications requiring formability and toughness after solution treatment.
