phosphorus copper silver brazing rods (2% silver)

silver brazing rods: Use for brazing,copper and copper parts in refrigerator and air conditioner,suitable for medium gap tie-in. Phos copper silver brazing alloys have good wettability,higher strength and toughness of brazing seam and lower melting point.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.
