介绍
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.

Forming
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.
焊接
这些合金的焊接可以使用所有商业方法轻松执行。在完成开发参数的实验试验之后，也可以进行铜管。
热工作
热工作可以在371至204°C（700至400°F）的铝 /铝5050合金上进行。
冷工作
铝 /铝5050合金的冷工作能力非常好，尤其是在退火形式下。
退火
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.
Hardening
铝 /铝5050合金可以冷来确保可耐用性。
Applications
Aluminium / Aluminum 5050 alloy is widely used in the manufacture of coiled tubes, refrigerator trim, and builder's hardware.
