→Silver-Metal Oxide Materials Ag/CdO, Ag/SnO2, Ag/ZnO
Very low and flat material transfer during DC load switching,<br />
Good arc moving and very good arc extinguishing properties
|-
|Ag/ZnO<br />DODURIT ZnO
|Environmentally friendly materials,<br />
High resistance against welding during current on switching<br />(capacitor contactors),<br />
Low and stable contact resistance through special oxide additives,<br />Very high arc erosion resistance at high switching currents,<br />
Less favorable than Ag/SnO<sub>2</sub> for electrical life and material transfer,<br />
With Ag<sub>2</sub>WO<sub>4</sub> additive especially suitable for AC relays
