Abstract

Alloy 2124 is a heat treatable plate alloy that was developed for elevated-temperature application. Copper is the main alloying addition. 2124-T851 plate is an improvement in fracture toughness compared to 2024-T851. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness, creep, and fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: AL-399. Producer or source: Alcoa Mill Products.
