Alcoa 2324-T39 Aluminum Plate
Categories:	Metal; Nonferrous Metal; Aluminum Alloy; 2000 Series Aluminum Alloy
Material Notes:	Alloy 2324-T39 is a higher strength version of alloy 2024-T351 and is a purity controlled composition variant of alloy 2024. It was developed for tension-dominated, fatigue and fracture critical plate applications. The T39 temper, developed through special fabricating practices, improves both strength and fracture toughness properties over alloy 2024 plate. Alloy 2324-T39 plate is being used successfully on lower wing skin and center wing box components of commercial aircraft. Information provided by Alcoa.
