Amdry 7801

Amdry 7801 is a nickel-based, chromium-free, braze filler metal with a composition of AWS BNi-3 and AMS 4778 (grade 140C). Its relatively low melting temperature makes it a good candidate when the braze temperature has to be kept low, and its excellent ductility makes it a good choice for applications that undergo stress in service. Braze in vacuum, argon, or dry hydrogen atmospheres. Amdry 7801 is available as a powder. It is available as a paste or customized tape on request.
