Brazing Alloys
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 Because of the toxicity of cadmium most cadmium containing brazing alloys have been replaced by zinc and tin containing brazing alloys.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.
