Description / Abstract:
Form
This specification covers an aluminum alloy in the form of
rolled or forged rings.
Application
These rings have been used typically for high strength machined
parts where good stability is required during machining, but usage
is not limited to such applications. These rings are not
recommended for fusion welding.
Certain design and fabricating procedures may cause these rings
to become susceptible to stress-corrosion cracking; ARP823
recommends practices to minimize such conditions.
Classification
Rings are classified by type of mechanical stress relief as
follows:
7075-T651 Stress relieved by tension
7075-T652 Stress relieved by compression
Either type may be supplied, unless a specific type is
ordered.
