5、d 2009-06 Revised 2015-12 Superseding AMS4763A Silver Alloy, Brazing Filler Metal 56Ag 22Cu 17Zn 5.0Sn 1145 to 1205 F (618 to 652 C) Solidus-Liquidus Range (Composition similar to UNS P07563) RATIONALE AMS4763B incorporates the industry standard requirements of AWS A5.8 and is a Five Year Review and

6、 update of this specification. 1. SCOPE 1.1 Form This specification 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 Application This material has been used typically for joining ferrou

7、s metals and alloys, requiring good joint strength up to 600 F (316 C) for short-time service or up to 400 F (204 C) for long-time service, and for joining nonferrous metals except those having a base of titanium, aluminum or magnesium, but usage is not limited to such applications. 1.2.1 The low br

8、azing temperature and the tin content help to inhibit stress corrosion cracking during brazing of nickel base alloys. 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 the extent specified herein. The suppli

9、er 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. 2.1 SAE Publications Available from SAE Internation
