Solid Rivet

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 the 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.

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 are widely

used in 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.

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

substituted by other materials.

AgSnO2 series (Cd free)

This material is produced by dispersing SnO2 Oxidation in silver base produced by

powder method and keeps 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 material. Especially, this material possesses excellent properties

for the use of relay and switch at heavy load area of DC.

AgSnO2In2O3 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 the 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.

AgCu series

Anti-discoloration decreases depending on the content of copper, while hardness and

mechanical anti-abrasion increases. Contact strength is strong and it is not usable

if there is a sliding contact when it operates.
