Alcoa alloy 2090-T83 is an aluminum-lithium sheet alloy with a combination of strength, low density, and corrosion resistance. The alloy is used in aerospace applications. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on corrosion resistance as well as joining. Filing Code: AL-371. Producer or source: Alcoa Mill Products Inc.

ALCOA Alloy 2090 is an aluminum-lithium alloy with 8% lower density and 12% higher elastic modulus than 7075-T6, a major high-strength alloy used in aircarft structures. Special facilities and practices required for casting commercial size aluminum-lithium ingots have been developed to cope with the highly reactive nature of lithium in molten aluminum. In general, the alloy should be considered for use in light-weight structures requiring high strength and stiffness. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on low and high temperature performance, and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Al-299. Producer or source: Aluminum Company of America.

Alcoa 2099-T86 is a low density, high strength plate alloy available in the T86 temper. 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-450. Producer or source: Alcoa Aerospace and Automotive Products.
