PHOSPHORUS SILVER BRAZING ALLOYS

Veer Brazing alloys are the cleanest and brightest, free of oxide and surface impurities. These brazing alloys are extensively used for joining copper tubing in the refrigeration and air conditioning industries, as well as in other application. Phosphorus acts as a fluxing agent due to its affinity for oxygen, therefore the usual application of a brazing flux may be omitted. However, this type of brazing alloys cannot be used on Ferrous or Nickel alloys because of brittle joints.
Leaks are caused by oxide and impurities. Contamination that enters the joint in the molten metal of an impure brazing alloy and impede the brazing alloy flow. Wherever there is contamination, the alloy flows around it, leaving pinholes in the joint. These pinholes are tiny doors which allow refrigerant gas to leak out. Leaks are expensive; the serviceman has to return to the job to re-braze the joint and must refill the expensive refrigerant that was lost from the leaks.
