These alloys are excellent for joining copper to copper where the phosphorus content of the phos-copper-silver brazing alloy reacts with the copper of the base metal in such a way that the filler metal becomes “self-fluxing”. For this reason these alloys are used quite extensively for joining closed copper tubing in the refrigeration and air conditioning industries where flux removal after brazing is difficult to impossible. Washington Alloy Phos-Copper-Silver Brazing Alloys are also used to join copper to brass and brass to brass, however, when joining these combinations a paste flux is recommended. Please keep in mind that these alloys are not to be used on iron or steel, nickel based alloys or any alloy containing more than 10% nickel due to the possibility of “phosphorus embrittlement”. Basically the phosphorus of the filler metal reacts with iron or steel or nickel to create a weakening condition known as phosphorus embrittlement. Washington Alloy Phos-Copper-Silver Brazing Alloys offer excellent corrosion resistance except when exposed to sulfurous atmospheres. Commonly used in the plumbing, heating and electrical industries.
