The alloys can be soft soldered readily. This technique is not however normally employed because of
the inadequacy of the joint strength in service conditions for which copper-nickel alloys are specified
and problems of bimetallic corrosion which may arise in aggressive environments. Of the
conventional brazing methods available, the use of high silver filler alloys is strongly recommended
to minimise selective corrosion risks. Copper-phosphorus and copper-silver-phosphorus brazing
alloys should not be used due to the possibility of intergranular penetration and consequent
embrittlement. Heavily cold-worked material should be annealed before brazing to avoid excessive
penetration and cracking of the parent metal by the brazing alloy.
