Detailed Product Description

Silver rivet and Ag/Cu bimetal rivet:
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. It is
easily soldered and is the ideal contactor material for continuous, enclosed electric
connectors. It is one of the most widely used materials in small capacity
and low voltage electrical appliances, such as automatic control switches,
thermostats, baking machines, oven, timers, thermal relays, and computers.

AgCu rivet:
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.

Fk Ag contact rivet:
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.

AgNi /Cu bimetal 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.

AgCdO/Cu bimetal rivet:
This contact includes AgCdO10, AgCdO12, AgCdO15, 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 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.

AgZnO rivet and AgZnO/Cu bimetal rivet:
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.

AgSnO2 and AgSnO2 In2O3 and bimetal rivet:
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.

This kind of electrical contact will be widely used in 2005, and our product have
passed the certificate of SGS.
