For electrical contacts usually low-melting alloys with a minimum of 20 wt-% silver and additions of cadmium, zinc or tin to lower the melting point are used <xr id="fig:Commonly Used Brazing Alloys for Electrical Contacts"/> (Table 4.1). Because of the toxicity of cadmium most cadmium containing brazing alloys have been replaced by zinc and tin containing brazing alloys. For higher requirements on corrosion resistance or for easier wetting of stainless steel nickel and manganese containing alloys are also used. Using any of these brazing alloys in an air environment is only possible with the addition of oxide reducing fluxes.

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.
