    5、5 Aluminum Alloy Extrusions 7.8Zn - 2.6Mg - 2.0Cu - 0.10Zr - (7068-T6511) Solution Heat Treated, Stress Relieved, and Precipitation Heat Treated RATIONALE This document has been reaffirmed to comply with the SAE five-year review policy. 1. SCOPE: 1.1 Form: This specification covers an aluminum alloy

    6、 in the form of extruded bars, rods, shapes (profiles), and tubing. 1.2 Application: These extrusions have been used typically for structural parts requiring a combination of high tensile strength and moderate fatigue strength, but usage is not limited to such applications. 1.2.1 Certain design and

    7、processing procedures may cause these products to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions. 2. APPLICABLE DOCUMENTS; The issue of the following documents in effect on the date of the purchase order forms a part of this specification to

    8、the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been canceled and no superseding document has been specified, the last published issue of that document shall apply. 2.1 SAE Publi

QUALITY ASSURANCE PROVISIONS: 4.1 Responsibility for Inspection: The vendor of extrusions shall supply all samples for vendors tests

    22、 and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the products conform to the specified requirements. 4.2 Classification of Tests: 4.2.1 Acceptance Tests: Composition (3.

    23、1), tensile properties (3.3.1), ultrasonic inspection (3.4.1) when specified, and tolerances (3.5) are acceptance tests and, except for composition, shall be performed on each inspection lot. 4.3 Sampling and Testing: Shall be in accordance with AMS 2355. 4.4 Reports: 4.4.1 The vendor of extrusions
