These alloys are used for their high electrical conductivity, for their absence of toxicity in the food industry, for their ductility in the processing of copper and its alloys on solid pieces. These alloys are suitable for all steels, for copper and copper alloys, for nickel alloys. TOP TEC 1 TOP TEC 2 TOP TEC 3 TOP TEC 4 TOP TEC 5 Economic alloy but with low silver content; recommended for large series brazing, provided the heating method is particularly fast.
