2219 Aluminum Sheet Plate


2219 aluminum sheet plate is a high-strength Al-Cu heat-treatable alloy belonging to the 2000 series, widely used in aerospace and high-temperature structural fields. It features excellent weldability, high fracture toughness, and stable mechanical properties across an ultra-wide temperature range from -269°C to 315°C. Available in bare and alclad versions, it is the preferred material for rocket propellant tanks, cryogenic vessels, aircraft skins, and high-temperature components.
