Stay-Silv 15 PhosCopper Brazing Alloy, 0.050" x 1/8" x 36" Size, 1190 F Solidus, 1480 F Liquidus

Brazing Properties: Stay Silv 15 brazing filler metal is a frequent choice for brazing copper, especially in brazing air conditioning and refrigeration connections. The alloy has a wide melting range which allows the operator to fill loose connections and "cap" or build up around the finished joint. When heated above its liquidus temperature, however, it will flow into tight connections. Stay Silv 15 can be used to braze brass with the use of appropriate brazing flux. Stay Silv 15 is not recommended for brazing steel or other ferrous metals due to sufficient lack of joint ductility. It is generally suitable for brazing low nickel, (10% maximum), copper/nickel base metals.Corrosion Resistance: Generally similar to the copper base metal, but phosphorus containing alloys, including Stay Silv 15, should not be used if the braze is exposed to sulfur or sulfur compounds in service.Specification Compliance: ANSI/AWS A5.8 Class BCuP-5, ASME SFA 5.8 Class BCuP-5, QQ-B-654A BCuP-5, ISO 17672 CuP 284Recommended Flux: No flux is required for copper brazing. For brazing brass or copper to brass Stay-Silv white flux is suitable for most applications. Harris Eco Smart boric acid free flux, (powder or paste), is also an excellent choice to promote sound brazed assemblies and comply with European Reach requirements.
