Manufacture silver contact point/contact point/electrical silver contact

 Manufacture silver contact point/contact point/electrical silver contact    Product overview: Silver-based contact tips are available in many different versions, with different designs and material contents, using the method of welding and brazing at the bottom side. They are wildly used in various kinds of contactors, relays, circuit breaks and switches, etc.    Main Materials: AgNi, AgSnO2, AgCu, AgZnO, AgCdO.   AgZnO Features: (1) ZnO, one type of material in AgznO contact, has comparatively higher thermal stability (2) The welding resistant and resistance against arc erosion of the contact making ZnO material a higher product (3) The AgZnO contact material has higher welding resistance and low arc erosion with strong magnetic arc blowing under large switching capacity (4) AgZnO contact material is innocuous and has no pollution to the environment (5) AgZnO contact material is mostly suitable for contactors and circuit breakers with large capacities   AgZnO physical property:   AgNi sheet  (1) AgNi contact material contains 10% to 40% Ni; (2) Produced by powder metallurgical production, with low and stable contact resistance, high hardness and mechanical strength (3) Material transfer in case of DC is very low; (4) High electrical and thermal conductivity ; (5) With very low arc erosion. On making higher current, normally asymmetric pairs  with AgC contact materials are applied; 6) Wire of solid and composite rivets produced by powder sintering-extruding methods;   AgSnO2 sheet (1) AgSnO2 is the ideal material of AgCdO and has excellent properties of contacts; (2) AgSnO2 has higher thermal stability; (3) AgSnO2 has higher resistance against welding and erosion than AgCdO material ; (4) Non-poisonous. So it is a new material which is empoldered and developed actively over the world;  (5) For AgSnO2 contact material, the contact resistance can be controlled within thelimited range by putting in a small amount of additive of special metal-oxide; (6)  In this aspect, contact materials produced by powder metallurgy processing method have higher resistance against arc erosion and less arc bumming than those produced by oxidation processing method;   AgCdO sheet   (1) AgCdO is a kind of most important contact material among silver metal-oxide materials, and it is widely used for low-voltage  devices; (2) When the temperature is higher than 900centigrade, CdO is sublimated and the contact surface is cooled down in order to reduce and even extinguish   the arc energy.  This method can increase the resistance against welding. (3) Contact materials produced by powder sintering-extruding methods have higher density and low resistance rate (4) It also has higher welding resistance and uniform arc erosionInner   1:Type: Round type/ rectangular type,head dimension: round tip:2mm-25mm rectangular tip: W=3mm-20mm,L=3mm-25mm;tip thickness:0.5mm-3.0mm 2:Application: Highmediumlow voltage breaker, automatic switch, highmediumand low voltage electrical appliance   3: Radius can be customers size. 4: Products range: wall switch, relay, breaker, thermostat, mid/low voltage switch 5: ROHS compliance: as per customers requirement 6: Customized OEM/ODM orders are welcome: Yes 7: Resistant to high-current, high current, Kang Da current corrosion and welding, hardness, strength is higher than normal contacts           PACKAGE PICTURES:     VARIOUS SILVER CONTACT SHEETS CAN BE PRODUCED ACCORDING TO CUSTOMER'S REQUIREMENT IF YOU HAVE ANY QUESTIONS,PLEASE FEEL FREE TO CONTACT US!
