|Ag/CdO<br />DODURIT CdO
|High resistance against welding during current on switching for currents up to<br />5kA especially for powder metallurgical materials,<br />
Weld resistance increases with higher oxide contents,<br />
Low and stable contact resistance over the life of the device and good<br />temperature rise properties,<br />
High arc erosion resistance and contact life at switching currents<br />
of 100A – 5kA,<br />
Very good arc moving properties for materials produced by internal oxidation,<br />Good arc extinguishing properties,<br />
Formability better than the one of Ag/SnO2 and Ag/ZnO materials,<br />
Use of Ag/CdO in automotive components is prohibited because of Cd toxicity,<br />Prohibition of use in consumer products and appliances in EU.
