Copper-Phosphorus Brazing Filler Metals

Copper-phosphorus brazing alloy 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 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.
