Characteristics / Applications:

           Copper and phasphorous are principle elements of the product,it owns good fluidity and is applied in the resistance brazing,flame brazing and high frequency brazing.It is used in brazing of copper and copper alloys,but not in brazing of ferrous metals.The product is applied widely in the industries of refrigeration,household appliance,electric machinery,electric appliance and instrument etc.Flux is unnecessary when brazing copper as phosphorous plays a role of flux.Cleaning the surface of brazing metals strictly before brazing is necessary to remove the dirty such as oil dirties,oxides etc.   

        Our copper phasphorous rings set the world standard.Our automated inspection process and precise alloy control assure you of precise fit and consistent flow every time.We offer single turn,multiple turn and flat wire in a wide variety of alloys.
