For electrical contacts, usually low-melting alloys with a minimum of 20 wt-% silver and additions of cadmium, zinc or tin are used to lower the melting point (<xr id="tab: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 Because of the toxicity of cadmium, most cadmium containing brazing alloys have been replaced by zinc and tin containing brazing alloys. Alloys containing nickel and manganese are also used for higher corrosion resistance requirements or for easier wetting of stainless steel.. 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.
