Electric contact Future
Pure sliver has a high level of electrical and thermal conductivity,good plasticty and arc corrosion resistance,as well as a very low contact resistance.It is easlily soldered and is the idealcontactor material for continous,enclosed electric connectors.It is one of most wildely used material in small capacity and low voltage electical appliances, such as automatic control switches,themostats,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 slivers 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 is wildely used in AC contactors,relays,eletric tool switches,buttons,timers and other household electrical appliances.
AgNi/Cu bimetal rivet
In low voltage engineering,this contact is wildely 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 layer,thus making manufacturing of contactor components simple and ecnormical.
AgCdO/Cu bimetal rivet
This contact includes AgCdO10, AgCdO12.,AgCdO15 and this kind of electrical contact has one of the most important materials in sliver-metal oxide contact material.The fine CdO gives thes contact special properties.When the temperature is above 900 degrees,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 appliation include low voltage contactors relays, automatic switch flash relays,,auxiliary switch series,timers starters,breakers and leakers protective switches.
AgZnO rivets 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 and bimetal rivet
AgSnO2 and AgSnO2In2O3 are the ideal environment-protecting materials for substituting AgCdO.Since SnO2 has better thermal stability and higner hardness than CdO, AgSnO2 and AgSnO2In2O3 is higher and it is moer difficult to processing these two materials.
