Silver Contact Point

Product Description

1).Pure silver rivet
2).AgCu rivet:
This contact has good electrical conductivity and its surface is not liable to oxidization. The addition of 3 - *8% copper may remarkably improve the silver's flame resistance. Hence, copper contact material may be used in current strength up to *6A. The addition of copper, especially of high copper content, for example *0%, will greatly reduce material transferring during DC working conditions. It is widely used in AC contactors, relays, electric tool switches, s, timers, and other household electrical appliances.


3).Fk Agcontact rivet:
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. Its fusion welding and flame resistance is slightly higher than that of pure silver, and under almost equal contact resistance, its strength and heat resistance are higher than that of a silver-copper composite contactor. It is suitable for various temperature adjustments of working current <*0A.

4).AgNi /Cu Rivet
In low voltage engineering, this contact is widely used in AC switches as an electrical contact. Its advantages include that it may be directly soldered to contact bridges, without the need for additional solder layers, thus making manufacturing of contactor components simple and economical.

5).AgCdO/Cu rivet
1)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. The fine CdO gives the contact special properties. When the temperature is above**0oC, CdO sublimes, which cools the contactor surface and reduces arc energy and extinguishments. In addition, existence of cadmium oxide will improve


6.)AgSnO2 and AgSnO2 In2O3 and bimetal rivet tri-metalrivet
1)AgSnO2 and AgSnO2In2O3 are the ideal environment-protecting materials for substituting AgCdO. Since SnO2 has better thermal stability and higher hardness than CdO, AgSnO2 and AgSnO2 In2O3 is higher and it is more difficult to processing these two materials.
