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.
