A complete list of the uses of Easy-Flo 45 would include practically all applications for which silver brazing filler metals have been used.
Characteristics: Easy-Flo 45 is a 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-1, SAE-AMS 4769, ASME Boiler and Pressure Vessel Code Section II-C SFA 5.8 BAg-1
