AMS4774 Silver Alloy, Brazing Filler Metal, 63Ag - 28.5Cu - 6.0Sn - 2.5Ni, 1275 to 1475 °F (691 to 802 °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, including austenitic steels and alloys, requiring moderate joint strength up to 700 degrees F (371 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, magnesium, or titanium, but usage is not limited to such applications.
