METGLAS MBF-80A is a brazing foil in ductile, flexible metallic-glass form (a similar grade, MBF-80, is identical except that it has larger dimensional tolerances). It provides high-strength brazements at elevated temperatures and good moderate-temperature resistance to oxidation and corrosion. Its sluggish flow fills wide gaps up to 0.100 mm (0.004 inch). It is an excellent choice for diffusion brazing. 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-290. Producer or source: Allied Corporation.
