Silver Alloy Wire

I Ag series: 
Silver and fine silver possess very high electric and thermal conductivity. Low and
stable contact resistance and good processing and welding performance. 
Because of a little nickel added into silver, fine silver has higher intensity and
thermal-resistance performance than silver under same contact resistance. Therefore
its fusion resistance and arc burning resistance are better than that of silver.
Under the same application condition, fine silver can take the place of silver.

II AgNi series:
AgNi material with 10-40% of high melting-point metal nickel has high electric conductivity, low contact resistance and little burning loss. This material has little
transfer when connecting and breaking direct current. AgNi material is widely
used to AC and DC low-voltage devices, such as relays, instruction 
switches, can switches, assisting contactors. Instrument switches, optical control
switches, temperature controller and washing machine timers.

III AgCdO series:
AgCdO is the most used contact material at present. CdO obviously increased the fusion resistance or cohesive resistance of the contacts at the moment of getting
through big current. The sublimation of CdO cools the contact surface. 
Lowers the arc energy and extinguishes the arc. Therefore AgCdO can meet the main
requirements of low-voltage apparatus to contacts. Such as arc burning resistance
at big-current switching-on, low and stable contact resistance under various
loads and good arc extinguishing performance. Since Cd pollutes the environment.
It is being substituted by other materials.

VI AgSnO2 series (Cd free):
This material is produced by dispersing SnO2 oxidation in silver base
using produced by powder method and keep up superior electric conductivity with
improved anti-arc, anti-fusion, anti-abrasion. This material, as silver oxidation
dispersed strengthening Type alloy dispersion, features that SnO2 is
thermally stable and AnO2 is distributed fully on Ag metrics as a high
anti-arc, anti-fusion, anti-abrasion pre-oxidizer materials. Especially, this material
possesses excellent properties for the use of relay and switch at heavy
load area of DC.

V  AgSnO2 In2O3 series (Cd free):
This is the superior material in the properties of anti-fusion and anti-abrasion
under various load conditions because it is Cd-free material, now one of serious
environmental issues, and it is produced by internal oxidization method alloying
Ag-Sn alloy with many additive elements. This is used for AC and DC load.

VI AgCu series:
Anti-discoloration decreases depend on the content of copper, while hardness and
mechanical anti-abrasion increases. Contact strength is strong and it is not usable
if there is sliding contact tact when it operate.
