Material Notes:
Applications: This solder has been used where alloys melting higher than soft solders are required but the strength of standard solder brazing filler metals is not necessary. An example of this is the use in thermostatic bellows where the operating temperature is too high for soft solders and the bellows must be joined below their annealing temperature. A large use has been on small electric motors for soldering copper leads which would fail on overheating if soft soldered. Another use has been in soldering gun parts, replacing soft solders, In this case the advantages are strength at higher temperatures than soft solders can withstand and an increase in the corrosion resistance to alkaline solutions used in blackening gun barrels.Because of the high cadmium content of the filler metal, it should not be used for joining food containers. Characteristics: The flow point of Braze 503 is intermediate between soft solders and standard silver brazing filler metals. As a result, a special flux-Handy Flux Type TEC (a liquid flux) - has been developed for use with this filler metal, because the active temperature range of soft solder fluxes is too low while that of the silver brazing fluxes is too high. Braze 053, when used with Handy Flux Type TEC, will join such metals as copper, brass and steels. Information provided by Lucas-Milhaupt, Inc.
