Phos-Copper-Silver brazing alloys have a good wettability, higher strength and toughness of brazing seam and lower meltingpoint. The heating speed should be as quick as possiblewhile brazing. The joint is to be bright grey and will return to the originalcolor of bronzewhile dipped into 10% sulphuric Acid. Reuglar alloy nos includes JAgP-1 to JAgP-25, especially alloy JAgP-2 of Ag 1.8-2.2% and P 6.8-7.2% and rest for Cu used in HVAC industries, which is for easy flow, good solderability, plastic nature and better strength.
