Alcoa 2324-T39 plate is an age-hardenable high-strength version of alloy 2024 (Alloy Digest Al-23, August 1973, and Al-346, March 1998). The 2324-T39 alloy is used where higher strength; toughness, and good resistance to fatigue-crack propagation are needed. A typical application is the lower wing skin of commercial transport aircraft. This datasheet provides information on composition, physical properties, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance.
