300 degrees Fahrenheit within the life of each contact remained at 80000 to 100000 times Pure silver And Fing-grain Silver·Wire Materials·Electrical ContactsAg/Cu Composite ContactCharacteristic:Pure Silver possesses very high electrical conductivity, easy to produce and welding. When the trace elements are added to silver, the alloy will obtain a finer grain structure than pure silver, so that it possesses the qualities of electric conductivity and steady contact resistance like silver, the strength and hardness better than silver's and the electric life longer than that of pure silver. Silver-Nickel·Wire Materials·Electrical Contacts·AgNi/Cu Composite ContactsCharacteristic:The Silver-Nickel (AgNi) Contact Possesses high electrical conductivity, low-stable contact resistance, good wear resistance. And it's nontoxic. The material transfer in case of DC is very small. AgNi (10), AgNi (20) can be made from powder pressed sintered extrude. AgNi (30) can be made from powder pressed sintered repressed.Silver-Iron·Wire Materials·Electrical Contacts·AgFe/Cu Composite ContactsCharacteristic:Silver-Iron (AgFe) has good electric conductivity, heat conductivity, non-toxic, wear resistance. The contacts are produced by this material possesses high interrupting capability, low temperature rising. The materials can be made from coprecipitated powder pressed sintered extrude.Silver-Cadmium·Wire Materials·Electrical Contacts·AgCd/Cu Composite ContactsCharacteristic:Silver-Cadmium alloy (AgCd) has good electric conductivity and some ability of arc elimination, been used in carbon electrical apparatus and some instruments.Silver-Copper·Wire Materials·Electrical Contacts·AgCu/Cu Composite Contacts Characteristic:Silver-Copper (AgCu) has relatively high hardness and wear resistanc. The electrical contacts are mainly used in electrical apparatus which are sliding and rubing during on-and -off peration.Silver-Cadmium Oxide·Wire Materials·Electrical Contacts·AgCdo/Cu Composite ContactsCharacteristic:Good wear resistance, anti-welding,relatively constant contact resistance Cadmiun Oxide are spreaded all over the silver base, so the materials property increase in hardness and wear resistance.. It is beneficial to cooling and are-suppression vilent evaporation that the spread cadmium ordie particle can absofb large mumber of heat as decomposing under the arcing action, The Violent  evaporation blow off the arcing as decomposing, and purify the face of contacts. So it will reduce the wear resistance, increase in the electric life, and keep low contact resistance, silver_cadmium Oxide wires are made by advance oxidation method. Flap contacts added with the trace elements(T) are made by alloy in ternal oxidation method, and thebrazing side is silver.Silver-Tin oxide·Wire Materials·Electrical ContactsAgSnO2/Cu  Composite ContactsCharacteristic:The Silver-Tin Oxide Contact materials are produced by farina with especial technics, Good wear resistance. anti-welding, and decmposing under the arcing action, This contact have used in Ad, Dc connectior relay and low voltage breaker fields etc on..Silver-Tin oxide Indium Oxide·Wire Materials·Electrical Contacts·AgSnO2In2O3/Cu Composite ContactsCharacteristic:The Silver-Tin Oxide Indium Oxide (AgSnO2In2O3). materials combine good resistance to welding and stable contact resistance together with excellent to arc erosion, and is poisonous-less. It isActively developed and recommended material in the world. Silver –Tin Oxide Indium Ocide wires are made by advance osidation method. Flap contacts are made by alloy internal oxidation method , and the brazing side is silver ..
