4.Silver、silver alloy wires
Pure silver And Fing-grain Silver
Wire Materials
Electrical Contacts
Ag/Cu Composite Contact
Characteristic:
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 Contacts
Characteristic:
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 Contacts
Characteristic:
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 Contacts
Characteristic:
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 Contacts
Characteristic:
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 Contacts
AgSnO2/Cu Composite Contacts
Characteristic:
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 Contacts
Characteristic:
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 is
Actively 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 ..
