METGLAS MBF-35A is a brazing foil in ductile flexible metallic-glass form (a similar grade, MBF-35, is identical except that it has larger dimensional tolerances. It is a low-temperature filler metal foil designed for joining superalloys where the brazing operation should be done simultaneously during solution treatment. This foil exhibits excellent flow characteristics and will flow well into narrow joints. It is not recommended for use in severe corrosive atmospheres. This datasheet provides information on composition, physical properties, and microstructure. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: Ni-296. Producer or source: Allied Corporation.
