AMS4773A Silver Alloy, Brazing Filler Metal, 60Ag - 30Cu - 10Sn, 1115 to 1325 °F (602 to 718 °C) Solidus-Liquidus Range

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, particularly austenitic steels and alloys, requiring high joint strength up to 600 degrees F (315 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. This filler metal is particularly suitable for brazing in hydrogen or inert atmosphere.
