The Amdry™ 770 series of braze filler metals are spherical,
inert gas atomized, nickel braze alloys containing silicon and
chrome.
This alloy offers excellent strength and oxidation resistance at
temperatures up to 982 °C (1800 °F). The lower viscosity of
the molten alloy allows successful brazing of gaps up to
0.12 mm (0.005 in).
Amdry 770 filler metals are used in furnace brazing of aircraft
and aerospace components, commercial products such as
food processing equipment and heat exchangers. Components with joints that are exposed to high stresses in service
benefit from brazing with Amdry 770 filler metals. The lower
chromium content makes these filler metals good choices for
nuclear applications.
