Aluminium Alloy 2219

Technical Data Sheet

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.
