2219 aluminum alloy is a copper-containing wrought aluminum alloy designed for cryogenic and elevated-temperature aerospace applications, offering high strength retention at temperatures down to -452°F and excellent fracture toughness in thick sections. Primary uses include Space Shuttle external tank structures, rocket bodies, and other aerospace applications requiring superior strength-to-weight ratios combined with resistance to stress-corrosion cracking in the T8x temper conditions.
