Copper / Phosphorus alloy with 5% silver, having ductility and capillary flow characteristics between 17-2 AG and 17-15 AG. It provides the best combination of flow and ductility of all the silver-copper-phosphorous type brazing filler metals. Suitable for use in heating and ventilation industries, shipbuilding, refrigeration, and offshore and electrical industries.
It is recommended for use in the production of electric motors, dynamos and the joining of copper pipes in shipbuilding and offshore industries. It is extensively used in refrigeration, air conditioning and heat-exchanger components for fluxfree brazing of copper pipes and tubes. It is also used for joining copper in electrical engineering applications. Not suitable for brazing iron-containing materials like carbon, stainless steel, or materials with a nickel content as the phosphorus within the filler will form brittle compounds at the joint. For brazing copper to copper no flux is needed.
