Nickel Alloy, Brazing Filler Metal 82Ni - 4.5Si - 7.0Cr - 3.1B - 3.0Fe 1780 °F (971 °C) Solidus to 1830 °F (999 °C) Liquidus Range
AMS4777K
This specification covers a nickel alloy in the form of wire, rod, strip, foil, and powder and a viscous mixture (paste) of the powder in a suitable binder.
Rationale:
AMS4777K is the result of a Five-Year Review and update of the specification. The revision removes tolerance requirements, deferring to standard industry practice (see 3.5), and updates the prohibition on unauthorized exceptions to the specification (see 8.6).
