Amdry 775 is a nickel-based braze filler metal using only boron as the temperature supressent. It is a good choice for applications where silicon cannot be tolerated. Joints of Amdry 775 offer high hardness, with excellent joint strength, ductility, oxidation resistance and corrosion resistance. Braze Amdry 775 in vacuum furnaces or furnaces or atmospheres of argon or dry hydrogen. It is available as a powder. It can be ordered as a paste or customized tape on request.
