Description
Specification
Conditions of Use

The Silver Solder is most widely applied to form joints on the following materials:

· Copper tubes, pipes and fittings

·  Copper alloys including brass, bronze, nickel silver and aluminium-bronze

·  Electrical engineering applications

Part No. Chemical Composition(%) Melting Range(°C ) Characteristic & Application
Ag P Cu Solidus liquidus
SS2 1.8-2.2 6.8-7.2 Bal 645 788 SS2 sits between SS5 and copper phosphorus alloy. It is less ductile and free flowing than SS5 but more ductile whilst being less free flowing than copper phosphorus alloy. It is used in HVAC&R applications for flux-free brazing of copper pipes, tubes and seams where these properties and its cost are acceptable. It is also used in some electrical engineering and plumbing applications.
SS5 4.8-5.2 6.5-7.0 Bal 643 771 SS5 provides the best combination of flow and ductility of all the silver/copper-phosphorus type brazing filler metals. As a result it is extensively used in heat exchanger, air conditioning and refrigeration (HVAC&R) applications for flux-free brazing of copper pipes and tubes. It is also used for joining copper and copper alloys in electrical engineering applications.
SS15 14.5-15.5 4.8-5.2 Bal 645 800 SS15 is a widely used product being the most ductile of the silver/copper-phosphorus brazing filler metals and the only one available as a foil. It is used extensively in electrical engineering applications where it is used to make electrically conductive joints. It is also used in heating and ventilation and refrigeration applications to join copper pipes.

 

·  The Silver Solder is typically used for brazing in air with a welding gun, low melting point, high strength, good fluxility & wettability.

·  These products are self-fluxing when used on copper and therefore do not require a separate flux for this application.
