Easy-Flo 45 is a general purpose braze filler metal. The alloy can be used successfully on nearly all nickel, iron and copper base alloys. In certain instances, special fluxes may be required to obtain good wetting and bonding. In brazing gray cast iron it is necessary to treat the surface prior to brazing to remove graphite, in order to assure good wetting by the brazing filler metal. A complete list of the uses of Easy-Flo 45 would include practically all applications for which silver brazing filler metals have been used.
