In the aerospace field, aluminum alloy rings are key structural parts of heavy-duty launch vehicles and are used to connect the fuel tanks of multi-stage rockets. Aluminum alloy rings account for a large proportion of rocket structures and play an important role in the development of China's aerospace industry.

In the field of machinery, heated aluminum rings are suitable for disassembling cylindrical roller bearings and needle roller bearing inner rings without ribs or with one rib, especially suitable for small and medium-sized bearing rings.
