Phos/copper brazing, which joint has high strength ( generally greater than180 Mpa.)suitforbrazingcopper and copper alloys with low plasticity, and unfit to be usedin the impacted or curved state .Phos/copper filler metal has the self-brazing ability, so canbraze copper and silver without flux or braze copperalloy mixed with flux 102. Especially, itsfit with the brazing with torch, induction andresistance.The phosphor included in phos/copper alloy, together with iron, can produce brittlenesscompound,so this alloy cant be used to braze steel or other ferrous metals.
