Characteristics:
Puresilvercontact:
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 - *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.
Fk Ag
contact 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.
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 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 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.
