1.1 FormThis specification covers an aluminum alloy in the form of rolled or forged rings.1.2 ApplicationThese 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.1.2.1 Certain design and fabricating procedures may cause these rings to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.1.3 ClassificationRings are classified by type of mechanical stress relief as follows:7075-T651 Stress relieved by tension7075-T652 Stress relieved by compression1.3.1 Either type may be supplied, unless a specific type is ordered.
