2219 aluminum alloy (Cu-Mn primary alloying elements) is a high-strength aerospace material used in cryogenic tankage and structural applications requiring superior strength at low temperatures. The T852 temper (solution heat-treated, stress-relieved, and artificially aged) provides excellent damage tolerance and fracture toughness combined with high yield and tensile strength, making it suitable for critical pressure vessels and cryogenic service in hand-forged form per AMS 4144.
