Brazing Kit for High-Silver Alloy Work
The Harris Safety-Silv-45 kit supplies a 45 percent silver brazing alloy classified as BAg-5 for joining ferrous and non-ferrous metals. It includes a one-ounce coil of 1/16 inch diameter wire and a 1.75 ounce jar of paste flux. The kit suits maintenance technicians and fabricators who need a high-silver filler for strong, ductile joints.
Thermal Range and Flux Performance
The alloy melts between 1225 and 1370 degrees Fahrenheit with a solidus of 1225 and liquidus of 1370 degrees Fahrenheit. A fluidity rating of 6.5 indicates good capillary flow into tight joint clearances. The supplied paste flux protects the braze area from oxidation during the heating cycle.
Deciding Specification — Silver Content
The 45 percent silver content and the 1225 to 1370 degrees Fahrenheit working range determine suitability for the application. Lower-silver alloys melt at higher temperatures and may not provide the same ductility or corrosion resistance. Buyers needing a lower melting point or different alloy classification should select an alternative filler metal.

Questions about this item
How do I install the Safety-Silv-45 alloy coil and flux, and what step is most often missed?
Clean the joint until bright metal shows, apply the 1.75 oz flux paste evenly, then feed the 1/16 in alloy coil into the joint while heating to the 1225–1370 °F range; the step most often missed is pre-cleaning, which prevents the flux from wetting properly.
What maintenance or replacement will the brazing kit need later?
The 1 oz Safety-Silv-45 coil and 1.75 oz flux jar are consumables; replace them when the alloy runs out or the flux paste dries and can no longer protect the joint at 1225–1370 °F.
What limit appears first during sustained brazing with this alloy?
The fluidity rating of 6.5 means the molten alloy’s flow degrades first if the temperature drifts above the 1370 °F liquidus, causing sluggish fill and poor capillary action.
