Silver Alloy Wire
Silver Alloy Wire consist of soft, high-conductivity, oxidation-resistant materials used as the makeup of electrical components. They are the materials in a system through which an electrical current flows; such as:

  • Circuit breakers
  • Relays,
  • Switches,
  • EDM applications
  • earth leakage breakers
Silver Alloy Wire rivets comes in a variety of sizes. You can find options both small to extremely large, depending on your voltage requirements and usage.
Silver Alloy Wire are typically made from any metal with high electrical conductivity. However, in applications such as high-power equipment where mechanical wear is expected, a conductive metal may be used. Common electrical contact materials include:
  • Silver
  • Copper
  • Gold
  • Platinum
  • Palladium
  • Brass

Silver Alloy Wire Material Properties

When choosing the best Silver Alloy Wire for your application, it is important to keep in mind the six most important properties:

  • Conductivity
  • Corrosion Resistance
  • Hardness
  • Current Load
  • Cycle Life
  • Size

Silver Alloy Wire Conductivity

Conductivity refers to the measure of a materials ability to conduct or carry an electric current. You will see this as a percent of a copper standard (ex: 100% International Annealed Copper Standard or IACS) Silver, which has the highest conductivity, has an IACS of 105.

Corrosion Resistance

Corrosion resistance of electrical contacts refers to a material’s ability to resist chemical decay. Any material with little corrosion resistance will decay faster than ones with high resistance.


This measures how resistant materials are to various kinds of permanent deformations from an applied force. It is dependant on five factors:

  • Ductility
  • Elasticity
  • Plasticity
  • Tensile Strength
  • Toughness
Alloys composition
  • Silver Cadmium Oxide
  • Silver Graphite
  • Silver Tin Oxide
  • Silver Nickel


This information refers to silver cadmium oxide wires, profiles and contact tips manufactured by blending of silver and cadmium oxide powder,cornpacting, sintering, extruding and then drawing or rolling to final dimension. Profiles and tips are available with a brazeable silver backing layer.


The silver content is designated by the first number: e.gAg/CdO 88/12 with 88 wt.-% silver, balance CdO. The standard oxide contents are 10,12 and 15.


  • switches for domestic applications, main switches
  • earth leakage breakers, miniature circuit breakers
  • contactors
  • circuit breakers up to a switching current of 3000 A
  • power Line relays


  • excellent anti-welding properties on make, higher CdO content is improving anti-welding properties
  • low contact resistance compared to other metal oxides
  • contact resistance stable throughout the time life
  • low arc erosion,excellent arc extinguishing properties
  • tendency for material transfer in DC applications


The nature of our Production process leads to a certain orientation of the CdO particles along the direction of extrusion.
