Aluminum Alloy, Rolled or Forged Rings 5.6Zn - 2.5Mg - 1.6Cu - 0.23Cr (7075-T7351, 7075-T7352) Solution Heat Treated, Mechanically Stress Relieved, and Precipitation Heat Treated
|Publication Date:||1 January 2019|
This specification covers an aluminum alloy in the form of rolled or forged rings up to 6 inches (152 mm) inclusive, in nominal thickness at the time of heat treatment, and having an OD to wall thickness ratio of 10 or greater (see 8.6).
These rings have been used typically for applications requiring a combination of high strength, resistance to stress-corrosion cracking, and good stability during machining, but usage is not limited to such applications.
Rings are classified by type of mechanical stress relief as follows:
Type 1 - Stress-relieved by stretching (7075-T7351)
Type 2 - Stress-relieved by compression (7075-T7352)
Either type may be supplied, unless a specific type is ordered.
