Abstract
Disclosure is made of a method for brazing ferromagnetic materials whereby a metalloceramic braze, containing a ferromagnetic refractory component and a fusible component the melting point of which is lower than the Curie point for the refractory component, is placed in the gap between the materials to be joined. In the gap a magnetic field is created whose lines of force cross the gap and whose intensity is adequate enough to retain within the gap, the ferromagnetic refractory component in the process of brazing during the melting of the fusible component. The zone of joining the materials is heated to the temperature of brazing and then cooled. It is proposed also to use a metalloceramic braze, containing an alloy based on Cu--Co, consisting of 50-90% by weight of Cu, and a Cu-Mn-Ni alloy, containing 50-66% by weight of Cu, 24-34% by weight of Mn, and 2-16% by weight of Ni.
