Alloy 6013 aluminum sheet and plate is a new medium strength aerospacealloy that provides improved formability, lower density and corrosion resistance.  The T4 condition allows 6013 aluminum sheet to be formed and demonstrates better stretch forming characteristics. The part can then be aged to the T6 condition without costly heat treating or annealing operations.  The yield strength is 12% higher than Alclad 2024 and resistant to exfoliation and stress corrosion cracking.
