→Brazing Alloys
For high temperature brazing in vacuum or protective atmosphere vacuum melted silver-copper eutectic brazing alloys are used. These also allow subsequent forming operations due to their higher ductility.
For the brazing of contacts with a silver bottom layer to copper backings phosphorous containing brazing alloys which eliminate the need for a flux application are widely used.
The brazing alloy is typically introduced into the joint area in the form of wire segments, foil, shims, or as powder or paste. For larger production volumes it is economically advantageous to pre-coat contact tips with a thin layer (< ≤ 100 µm) of brazing alloy.
