6、le 2, 4.2.1) to facilitate future cancellation of AMS-QQ-A-225/9.1. SCOPE1.1 FormThis specification covers an aluminum alloy in the form of bars, rods, and wire in the “as fabricated (F) temper. When specified, product shall be supplied in the annealed (O) condition.1.2 ApplicationThese products hav
7、e been typically used for parts requiring forming and as stock for flash welded rings which are to be subsequently solution and precipitation heat treated, but usage is not limited to such applications. 1.2.1 Certain design and processing procedures may cause these products to become susceptible to
8、stress-corrosion cracking after solution and precipitation heat treatment; ARP823 recommends practices to minimize such conditions.2. APPLICABLE DOCUMENTSThe issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein
9、. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply.SAE AMS4186D Page 2 of 52.1 SAE Publicat
