Advantages:

AgCdO(Silver - Cadmium Oxide) series: has good wear resistance, fusion welding resistance and electrical and thermal conductivity, small and stable contact resistance.
AgSnO2 (Silver - Tin Oxide) series: high thermal stability, heat resistance, arc erosion resistance and melting resistance, long service life
AgNi(Silver-Nickel) series: Used for DC contacts with good electrical conductivity, stable contact resistance, small electrical loss. AgSnO2ln2O3 (Silver - Indium Tin Oxide) series: better thermal stability and higher hardness, with better fusion welding and durable burn out.
Pure Silver: good conductivity, but easy to stick and weld.
