Lucas-Milhaupt EASY FLO Silver Based Cadmium-Bearing Filler Metal

Applications: Easy-Flo is very versatile and 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 would include practically all applications for which silver brazing filler metals have been used. Characteristics:Easy-Flo is a are eutectic type, free-flowing filler metals that, because of their narrow melting range, are less sensitive to the rate of heating and should not liquate (i.e. separate into low and high melting constituents). This high fluidity makes well-fitted joints essential and prevents bridging or large fillet formation. Handy Flux should be used with either of these filler metals.Some base metals when brazed under high stress may crack during brazing when the stressed base metal is wetted by the brazing filler metal. This is a form of stress corrosion cracking. The low flow temperature of Easy-Flo is below the stress relaxation temperature of some nickel base alloys. The cure is to relieve the stress before the brazing alloy is applied. A higher melting brazing filler metal may be preferred since stress relief will then occur before the filler metal melts. Specifications:This filler metal conform to the following specifications: AWS A5.8 BAg-1a, SAE-AMS 4770, ASME Boiler and Pressure Vessel Code Section II-C SFA 5.8 BAg-1a Information provided by Lucas-Milhaupt, Inc.
