|---|---|
2219 aluminum alloy is an alloy in the wrought aluminum copper series. It can be heat treated to produce a stronger but less ductile temper. Aluminum-copper alloys have high strength, but are generally less resistant to corrosion and more difficult to weld than other types of aluminum alloys. To compensate for the lower corrosion resistance, 2219 aluminum can be clad with a commercially pure alloy such as 1050 or painted. This alloy is usually formed by extrusion and forging, but not for casting.
Chemical Composition
Aluminium: 91.5 to 93.8%
Copper: 5.8 to 6.8%
Iron: 0.3% max
Magnesium: 0.02% max
Manganese: 0.2 to 0.4%
Silicon: 0.2% max
Titanium: 0.02 to 0.10%
Vanadium: 0.05 to 0.15%
Zinc: 0.1% max
Zirconium: 0.10 to 0.25%
Residuals: 0.15% max
In particular, 2219 aluminum alloy has high fracture toughness, weldability and resistance to stress corrosion cracking, so it is widely used in supersonic aircraft skins and structural parts. Shuttle standard weight fuel tanks are also made of 2219 alloy.
