Sn 7.0~8.0 Ni 0.4~1.2
Copper phosphorus is principle elements of the product, with the tin, antimony and other elements. Brazing temperature is low. It 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 appliances, electric machinery, electric appliance and instrument etc. Flux is unnecessary when brazing copper as phosphorus 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.
