METGLAS MBF-75A is a brazing foil in ductile, flexible metallic-glass form (a similar grade, MBF-75, is identical except that it has larger dimensional tolerances). It has excellent high-temperature strength and flows readily into narrow joints. Its high solidus temperature facilitates heat treatment of some superalloys without remelting the joint. It is recommended for joining high-temperature alloys and stainless steels. This datasheet provides information on composition, physical properties, microstructure, and hardness. It also includes information on joining. Filing Code: Ni-286. Producer or source: Allied Corporation.
