... intermetallic compound, nickel phosphide. The use of a brazing alloy containing phosphorus was unsuitable on two counts and a quaternary alloy containing silver, copper, cadmium and zinc, such as those in group AG1 or AG2 of BS 1845 would be more suitable. However, because corrosive problems experienced...

The undercutting and erosion effects may also occur in the brazing of aluminum and magnesium as well as the high-temperature alloys. Mutual solubility of copper and silver is very pronounced during the silver...

... on lead, new lead-free solders had to be developed. The most common replacements are tin–copper, tin–silver, and tin–silvercopper. All three alloys have similar solderability property to the lead-tin solders they are replacing. However, one property they do not possess is an inherent resistance...
