Application
Plate Aerospace The combination of high strength and fracture toughness properties and corrosion resistance makes 7065 suitable as a replacement for 7010, 7050, 7075, 7475 and other alloys for critical intermediate thickness applications. Spar, rib, and integrally machined structural parts for new, derivative, or retrofit aircraft.
