METGLAS MBF-60A is a brazing foil in ductile, flexible metallic-glass form (a similar grade, MBF-60, is identical except that it has larger dimensional tolerances). It is an excellent choice of filler metal for large production runs of low-to-medium stressed assemblies. Its excellent flow characteristics and low joint erosion recommend its selection, despite the fact that it has only moderate strength in comparison with other filler metals of this family. It is boron-free and thus is recommended for nuclear reactor applications. This datasheet provides information on composition, physical properties, microstructure, and hardness. It also includes information on forming, heat treating, and joining. Filing Code: Ni-278. Producer or source: Allied Corporation.
