Description:Product Name: Composite ContactPlace of Origin: ChinaSilver-copper composite contact (Ag/Cu): This contact has good electrical conductivity and its surface is not liable to oxidization. The addition of 3 - 28% copper may remarkably improve the silver's flame resistance. Hence, copper contact material may be used in current strength up to 16A. The addition of copper, especially of high copper content, for example 10%, will greatly reduce material transferring during DC working conditions. It is widely used in AC contactors, relays, electric tool switches, buttons, timers, and other household electrical appliances. Fine crystal silver-copper composite contact: This fine crystal silver contains a 0.12% 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 10A. Silver-nickel-copper composite contact (AgNi/Cu): In low voltage engineering, this contactor is widely used in AC switches as an electrical contactor. Its advantages include that it may be directly soldered to contactor bridges, without the need for additional solder layers, thus making manufacturing of contactor components simple and economical. Silver-cadmium oxide / copper composite contact (AgCdO/Cu): This contact includes AgCdO10, AgCdO12, AgCdO15, and this kinds of electrical contact has one of the most important materials in a silver-metal oxide contactor material. The fine CdO gives the contact special properties. When the temperature is above900oC, CdO sublimes, which cools the contactor surface and reduces arc energy and extinguishments. In addition, existence of cadmium oxide will improve the welding resistance of the contactor. Its typical applications include low voltage contactors, relays, automatic switch flash relays, auxiliary switch series, timers, starters, breakers and leakage protective switches. Silver zinc oxide / copper composite contact (AgZnO/Cu): The oxide of this contactor is more thermally stable than CdO. Because of the higher stability of ZnO and AgZnO, the contactor material increases the contactor resistance, which would be compensated through structural means, such as a higher contacting force.
