AMS 4777 is a nickel-chromium-silicon-boron-iron brazing alloy powder with low joining temperature. It provides high temperature joint strength plus oxidation, corrosion, and abrasion resistance on thick sections of stainless steel, ductile nickel, and cobalt base alloys. Typical applications would include structural members in jet engines, turbines, chemical processing and nuclear equipment (not exposed to radiation), requiring lower brazing/heat treatment temperatures.
