electrical contacts

详情

The contact material of this kind of silver contacts is usually AgCdO,AgSnOInO,AgNi... ...,the base material is copper
The silver contacts can be used in relay,switch,contactor,breaker,starter... ...
Different contact material for silver contacts has differentCharacteristic:

1. Ag/Cusilver contacts :Pure silver has a high level of electrical and thermal conductivity, good plasticity and arc corrosion resistance, as well as a very low contact resistance.
2. AgCusilver contacts : This contact has good electrical conductivity and its surface is not liable to oxidization.
3. Fk Agsilver contacts : This fine crystal silver contains a 0.*2% nickel additive and has a low contact resistance, which is similar to that of pure silver, without the variable switching times.
4. AgNi /Cusilver contacts : In low voltage engineering, this contact is widely used in AC switches as an electrical contact.
5. AgCdO/Cusilver contacts : This contact includes AgCdO*0, AgCdO*2, AgCdO*5, and this kind of electrical contact has one of the most important materials in silver - metal oxide contact material.  
6. AgZnO/Cusilver contacts :The oxide of this contactor is more thermally stable than CdO.
7. AgSnO2/Cusilver contacts: AgSnO2 and AgSnO2In2O3 are the ideal environment-protecting materials for substituting AgCdO.

(CECL)China Electrical Contacts Ltd. is located in Huizhou city ,Guangdong china,the company start to make electrical contacts since ***8, Under leadership of the telented engineer who has nearly *0 years experience on research and production of Electrician alloy materials and silver contacts, the company has developed electrician alloy products of outstanding electricity performance (High conductivitv、Low impedance、Low temprature rise、High electricitve life、high anti-welding) and fine machine-finishing performance. We mainly manufacture silver based electrical contact material, contact rivet and contact components, and plan to manufacture silver based electrical contact material **0ton, contact rivets 5 billion pieces annually. The products are widely applied in Microswitch、temperature controlled switch、Wall switch、relay、contactor、Automobile electric and other AC/DC starter. Moreover,each of the performance indexes indexes suroasses the national standards.
