2219 alloy typical applications
- Rockets and missile parts
- Aerospace fuel tanks
- Aircraft skin and structural components
- Other industrial applications
Description:
2219 aluminium alloy can be heat-treated to produce tempers with higher strength but lower ductility. The aluminium-copper alloys get high strength, but are generally less corrosion resistant and harder to weld than other types of aluminium alloys.
This alloy in particular has high fracture toughness, is weldable and resistant to stress corrosion cracking, therefore it is widely used in supersonic aircraft skin and structural members. The Space Shuttle Standard Weight Tank was also fabricated from 2219 alloy.
