1: Brief Introduction Of 2219 aluminum
2219 aluminium alloy is an alloy in the wrought aluminium-copper family (2000 or 2xxx series). It can be heat-treated to produce tempers with higher strength but lower ductility. The aluminium-copper alloys have high strength, but are generally less corrosion resistant and harder to weld than other types of aluminium alloys. To compensate for the lower corrosion resistance, 2219 aluminium can be clad in a commercially pure alloy such as 1050 or painted. This alloy is commonly formed by both extrusion and forging, but is not used in casting.[2]
The 2219 aluminium 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 the 2219 alloy.
Alternate designations include AlCu6Mn and A92219.
Machinability:
Aluminium /Aluminum 2219 alloy can be machined in the annealed condition. In the heat treated condition, this alloy is very difficult to machine. Oil base lubrication is used to perform machining operations.
Forming:
Aluminium /Aluminum 2219 alloy can be formed using conventional techniques.
Welding:
Aluminium /Aluminum 2219 alloy can be welded using resistance welding, and inert gas welding techniques with high precautions in order to prevent cracking. This process is followed by heat treatment in order to maintain the corrosion resistance property of this alloy.
Heat Treatment:
Aluminium /Aluminum 2219 alloy can be heat treated at 538°C (1000°F) followed by quenching in cold water.
Forging:
Aluminium /Aluminum 2219 alloy can be forged to maintain the corrosion resistance property.
Hot working:
Aluminium /Aluminum 2219 alloy should not be hot worked if they are not subjected to heat treatment in order to restore the corrosion resistance property of this alloy.
Cold working:
Aluminium /Aluminum 2219 alloy can be cold worked using conventional methods.
Annealing:
Aluminium /Aluminum 2219 alloy is annealed at 538°C (1000°F) for sufficient time followed by quenching in cold water.
Aging:
Aluminium /Aluminum 2219 alloy can be aged at 190°C (375°F) for varying time after annealing and quenching. Forgings can be aged at 190°C (375°F) for 18 h, and sheet or plate type product forms can be aged at 190°C (375°F) for 36 h followed by cooling in air.
Hardening:
Aluminium /Aluminum 2219 alloy is hardened by aging or cold working.
Applications:
Aluminium /Aluminum 2219 alloy is suitable for manufacturing structural components, which are used in high strength weldments and high temperature applications.
2: Chemical Composition
The aluminum industry has created a system using a four-digit numerical designation to identify wrought aluminum alloys. The first digit indicates the major alloying element. The second digit indicates whether there was a modification in the basic alloy. The third and fourth digit indicates the specific alloy. The following represent the various groups:
| 1XXX |
Aluminum 99% or greater |
| 2XXX |
Copper - major alloying element |
| 3XXX |
Manganese - major alloying element |
| 5XXX |
Magnesium - major alloying element |
| 6XXX |
Magnesium and silicon - major alloying elements |
| 7XXX |
Zinc -major alloying element |
