SCOPE1.1 FormThis speci

6、fication covers a silver alloy in the form of wire, rod, sheet, strip, foil, pig, powder, shot, and chips and a viscous mixture (paste) of powder in a suitable binder.1.2 ApplicationThis material has been used typically for brazing corrosion-resistant honeycomb structures and for joining alloys cont

7、aining minor amounts of aluminum or titanium, where service temperature will not exceed 900 F (482 C), but usage is not limited to such applications. Oxidation of the brazed alloy may occur during long-time exposure to such temperatures.2. APPLICABLE DOCUMENTSThe issue of the following documents in

8、effect on the date of the purchase order forms a part of this specification to 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 cancelled and no superseding document has been

9、 specified, the last published issue of that document shall apply.2.1 SAE PublicationsAvailable from SAE International, 400 Commonwealth Drive, Warrendale, PA 15096-0001, Tel: 877-606-7323 (inside USA and Canada) or +1 724-776-4970 (outside USA), www.sae.org.AMS2222 Tolerances, Copper and Copper All
