We are offering silver brazing rod. Silver 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. Phosphorous 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.
