Quick Details
Specifications
Silver nickel (AgNi) electrical contacts made of advanced materials, sintering,
extrusion technology, nickel fibrous particles were uniformly distributed.
Silver nickel (AgNi) electrical contacts of the contact resistance low and
stable, electrical conductivity, thermal conductivity, and the burning of small,
electric wear small and uniform, silver-nickel alloy (AgNi) electrical contacts
in DC under the opening and closing, the electrical contacts materials transfer
less than the silver contacts, especially for small enclosure off use; but
(AgNi) Silver nickel alloy electrical contacts in the oxide Ershi off electrical
contacts when the contact resistance increased, the sulfur-sensitive, high
current, resistance poor welding performance. (AgNi) nickel-silver electrical
contacts are usually associated with (AgNiC ) Silver graphite electrical contact
pair used. Silver nickel alloy material (AgNi) contains a special additive trace
significantly improve resistance to weld the material properties and resistance
to electrical wear. Mainly used in small enclosure in the high-load contact, the
contact with DC under the conditions; low-voltage, small current level of
contact, instrument switch, light control switches, relays, thermostat and
washing machine timer. The main products are nickel-silver alloy electrical
contacts AgNi, AgNi (10 ~ 20) / Cu Ag Ni / Cu composite electrical contact,
silver nickel / copper-nickel alloy - AgNi (10 ~ 20) / CuNi (8 ~ 10) composite
power contacts, etc.
