Form

This specification covers an aluminum alloy in the form of rolled or forged rings.

Application

These rings have been used typically for applications requiring a combination of high strength, resistance to stresscorrosion cracking, and good stability during machining, but usage is not limited to such applications.

Classifications

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.
