Amdry BRB-325 is a nickel-based, diffusion braze alloy with a fine particle size distribution. It is designed for restoration of stainless steel or superalloy components. Diffusing boron out of the braze joint produces a ductile, machinable deposit. Blend with a compatible superalloy filler powder when needed to repair very wide gaps. Joints provide good ductility and oxidation resistance with excellent strength and corrosion resistance. Braze Amdry BRB-325 in a vacuum furnace.
