Abstract:
1. A process for the cohesive joining of two or more metal parts comprising the steps of: a) providing a melt consisting of 3≦Ni≦10 atom %; 2≦Sn≦8 atom %; 0.5<Zn≦5.0 atom %; 8≦P≦15 atom %; remainder copper and incidental impurities; b) producing an amorphous brazing foil by rapid solidification of the melt on a moving cooling surface at a cooling rate of more than approx. 105° C./sec; c) forming a soldering composite by introducing the brazing foil between the metal parts that are to be joined; d) heating the soldering composite to a temperature above the liquidus point of the brazing foil; and e) cooling the soldering composite so as to join the metal parts.
