7050 T7451 aviation aluminum plate sheet is a high strength heat treatable alloy with high strength and resistance to spalling and stress corrosion cracking. Commonly used in aircraft structural parts for medium and heavy plate extrusions, free forgings and die forgings. The requirements for the manufacture of such parts are: resistance to flaking corrosion and stress corrosion cracking, fracture toughness and fatigue resistance.7050-T7451 aluminum plate has complete specifications and reliable quality. It is widely used in aviation, automobile, ship, electrical appliances, equipment and other fields.
7050 T7451 aviation aluminum plate
7050 aluminum plate is mainly used to manufacture aircraft structure and other high stress structural parts requiring high strength and corrosion resistance, such as aircraft upper and lower wing wall panels, stringers, etc. after solution treatment, it has good plasticity, good heat treatment strengthening effect, good strength below 150 degrees, and particularly good low-temperature strength.
7050 Alloy is used for aircraft lower wing panel
