The aluminum-lithium alloy 2099, also designated C460, was developed for use in aerospace and high-strength applications. The alloy has a lithium addition for lowered density compared to more conventional alloys. This datasheet provides information on composition, physical properties, tensile properties, and compressive strength as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as forming. Filing Code: AL-398. Producer or source: AEAP-Alcoa Engineered Aerospace Products.
