Harris Stay-Silv® 5
5% Silver PhosCopper Brazing Alloy
This medium-range alloy is well suited where close fit-up cannot be maintained. This filler metal is more ductile and flows better than Harris 0 or Stay-Silv® 2
Typical Application: Stay Silv 5 silver brazing filler metal is designed for copper to copper applications. It can also be used on copper to low zinc brass but this application requires use of Stay Silv white brazing flux. Like many phosphorus/copper brazing filler metals Stay Silv 5 will flow rapidly when heated quickly to its liquidus. This allows penetration into tight clearance connections. With slower heating the alloy melting range provides the ability to filler wider gaps. Stay Silv 5 is often chosen as an economical alternative to higher silver content alloys for copper and brass applications. Stay Silv 5 is not recommended for brazing steel or other ferrous base metals. In these applications the phosphorus content promotes formation of a low ductility intermetallic with the base metal.
