AMS4763A - Silver Alloy, Brazing Filler Metal, 56Ag - 22Cu - 17Zn - 5.0Sn, 1145 to 1205 °F (618 to 652 °C) Solidus-Liquidus Range

Document Number: AMS4763A
Revision Number: A
Title
Silver Alloy, Brazing Filler Metal, 56Ag - 22Cu - 17Zn - 5.0Sn, 1145 to 1205 °F (618 to 652 °C) Solidus-Liquidus Range
Scope
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.

This material has been used typically for joining ferrous metals and alloys, requiring good joint strength up to 600 degrees F (316 degrees C) for short-time service or up to 400 degrees F (204 degrees C) for long-time service, and for joining nonferrous metals except those having base of aluminum or magnesium, but usage is not limited to such applications.

The low brazing temperature and the tin content help to inhibit stress corrosion cracking during brazing of nickel base alloys.
