Aluminium / Aluminum alloys have excellent corrosion resistance. They are sensitive to high temperatures in the range of 200 to 250°C (392 to 482°F), and could lose some of their strength. However, the strength of Aluminium / Aluminum alloys can be enhanced at subzero temperatures, making them ideal low-temperature alloys.
Aluminium / Aluminum 5050 alloy is a wrought type alloy. It has excellent workability and is a non-heat treatable alloy. The following datasheet will provide more details about Aluminium / Aluminum 5050 alloy.

Fabrication and Heat Treatment
The machinability of Aluminium / Aluminum 5050 alloy is rated as fair, especially in the annealed condition. However, in cold worked conditions, the machinability is much better than that of the annealed material. Lubricants should be used while machining.
Formability of Aluminium / Aluminum 5050 alloy is excellent in the annealed or H32 temper form. The 5050 alloy can be formed with certain amount of difficulty when it is in the harder cold worked conditions.
Welding of these alloys can be easily performed using all commercial methods. Brazing is also possible after experimental trials to develop parameters are completed.
Hot working can be performed on Aluminium / Aluminum 5050 alloy at 371 to 204°C (700 to 400°F).
Cold working capacity of Aluminium / Aluminum 5050 alloy is excellent especially in the annealed temper form.
After the Aluminium / Aluminum 5050 alloy is extensively cold worked, annealing can be performed at 343°C (650°F) for a suitable amount of time so as to ensure thorough heating and then it can be air cooled.
Aluminium / Aluminum 5050 alloy can be cold worked to ensure hardenability.
Aluminium / Aluminum 5050 alloy is widely used in the manufacture of coiled tubes, refrigerator trim, and builder's hardware.
