Parts for forging engines of the same static strength as alloys but also requiring high resistance to stress corrosion cracking, such as aircraft and parts - landing gear cylinders and extrusions. The fatigue properties of the parts are roughly equal to that of the 6 alloy, while the toughness is slightly higher
Aircraft structural plate, extrusion, free forgings and die forgings. The requirements for the manufacture of such parts for the alloy are: anti-spalling corrosion, stress corrosion cracking resistance, high fracture toughness and fatigue resistance
