Fifteen different alloy systems were tested and studied for brazing characteristics, chemical and physical properties. These alloys were nickel base binary and ternary systems containing such metals and metalloids as phosphorus, silicon, chromium, manganese, molybdenum, tungsten and iron.
The nickel-phosphorus-chromium system and nickel-phosphorus- silicon system showed the best properties of the phosphorus bearing alloys. The nickel-silicon-manganese system showed the best properties of the silicon bearing alloys. Of the alloys studied the silicon bearing alloys in general are higher melting than the phosphorus bearing alloys.
Studies also showed that phosphorus and manganese contributed the most toward improving the flow and wetting properties of the alloys, while silicon and chromium contributed the most toward improving the oxidation resistance and strength properties of the alloys.
