Product Description
| Silver cadmium oxide | |||||||
| Silver cadmium oxide has good resistance to fusion welding and arc erosion due to the violent decomposition and evaporation of cadmium oxide under the action of arc. | |||||||
| Low and stable contact resistance. At the same time, silver cadmium oxide also has good processing properties. | |||||||
| Cadmium oxide has certain toxicity, and the increase of its content can improve the anti-welding performance of silver cadmium oxide materials, but it will increase the contact resistance and temperature rise. | |||||||
| At the same time reduce the processing properties of the material. |

| Silver tin oxide/silver tin oxide indium oxide | |||||||
| Silver tin oxide is the most ideal environmentally friendly low-voltage contact material for replacing toxic silver cadmium oxide. It has excellent resistance to fusion welding and arc erosion resistance. | |||||||
| Gradual replacement of silver cadmium oxide materials is widely used in contactors and general-purpose relays, magnetic holding relays, and automotive relays. Added 3~5wt.% | |||||||
| Indium oxide silver tin oxide indium oxide material has better resistance to material transfer under DC load conditions and is suitable for use in automotive relays and other fields. | |||||||
| In order to meet the diversity and individual needs of low-voltage electrical appliances, the company has developed a variety of silver tin oxide materials for use, with a tin oxide content of 8 to 16 wt.%. | |||||||
| The content of indium oxide is 0~5wt.%. The mechanical and physical properties and application of the main grade materials are shown in the following table. | |||||||
