Aluminium Alloy 2219 is a high strength alloy which combines good machinability and good mechanical properties. 2219 is useful over a temperature range of -452°F to 600°F, is readily weldable and has good fracture toughness. In the T8 condition it is resistant to stress corrosion cracking.
Aluminium 2219 is typically used in a range of aerospace applications such as high temperature structural applications including space booster and fuel tanks.
2219 Aluminum is a precipitation/age hardening alloy with excellent strength and mechanical properties. This copper-containing alloy features extreme toughness and excellent stress corrosion resistance when treated making it an excellent metal for use in supersonic aircraft component manufacture and high temperature structural applications.
