OUR PRODUCTS

ECI offers you a range of material alloys and form factors for your low, medium, or high
voltage applications that will surely meet your switches requirements. Our products are ISO
certified, cost effective, and delivered on-time.

Our products fall under the following categories:

We will have an alloy and manufacturing process that meets your needs
depending
on your required alloy, hardness, and electrical conductivity requirements.

Please see below for more specific details on your available range of material alloys
and form factors or contact us to discuss your needs.

In addition to the alloys listed above we offer Contact Assemblies joined by various methods: EB welding, hot bonding, resistance brazing, and induction brazing.

 

Your parts can be plated with standard plating of Gold, Silver, Electroless Nickel, or Copper and they can be all over plated or selectively plated using either rack and/or barrel process.

 

All of your contact materials and base copper materials are manufactured at our ISO certified mill. If the alloy you require is not listed above, please ask us if a custom alloy can be manufactured for you.

CONTACT MATERIAL
STANDARD PROPERTIES

Low Voltage

Fine silver exhibits the highest electrical conductivity (15.9 nΩ-m) of all the commercial metals, however due to its low mechanical wear resistance, affinity for sulfur to create surface oxides as well as high cost, alloys of it are most popular.

Medium to High Voltage

Fine silver exhibits the highest electrical conductivity (15.9 nΩ-m) of all the commercial metals, however due to its low mechanical wear resistance, affinity for sulfur to create surface oxides as well as high cost, alloys of it are most popular.

LOW VOLTAGE APPLICATIONS

Generally use elements of Fine Silver (Ag), and alloys of Silver Cadmium Oxide (AgCdO), Silver Tin Oxide (AgSnO), Silver Nickel (AgNi) and Contact Rivets (solid or bi-metallic).

 

Our internally oxidized grades (AgCdO and AgSnO) have a no Ag rich zones, and show a fully homogenized distribution of oxides as seen in our cross sectional microstructures that will be provided with your PPAP or First Article Report.

MEDIUM TO HIGH VOLTAGE APPLICATIONS

Generally use materials of Silver Graphite (AgC), Silver Tungsten (AgW), Silver Tungsten Carbide (AgWC), Copper Chromium (CuCr) and Copper Tungsten (CuW).
