Alloy 7040 is a variation of 7050, where Zr additions prevent recrystallization of hot-worked products during solution heat treatment without the quench sensitivity from additions of Cr.
7040-T7651 plates deliver an improved strength toughness balance compared to 7010 and 7050 alloys, and are ideal for structures needing high strength, high toughness, and good corrosion resistance, such as integrally machined spars, ribs, fuselage frames or other thick sections.
