Meltric Sales | Silver-Nickel Contact Materials


Meltric uses solid silver-nickel contact surfaces on almost all of its plug and receptacle product lines. The 85% silver/15% nickel composition of the contacts add the beneficial physical properties of nickel to the excellent electrical characteristics of silver.

This silver-nickel material provides significant advantages
over the brass materials used on most other types of plugs and receptacles.

Silver-Nickel Contact Tip
(85% Ag / 15% Ni)
  • Silver-nickel maintains its low contact resistance and superior electrical properties even after oxidation and tarnishing.
  • Silver-nickel withstands arcing very well and only welds at extremely high pressure and temperature.
  • Thanks to the influence of the nickel, silver-nickel provides excellent wear resistance.
  • Silver-nickel performs wells in and withstands wet and   corrosive environments.
The combination of the silver-nickel material with spring-loaded butt-style contacts provides an ideal contact for devices intended to repetitively make and break connections
under load.

Limitations of Brass as a Contact Material

In an oxidized state, silver-nickel is 20 times more conductive than brass
  • Brass is not arc resistant, so it is not suitable for repeated making and breaking under load.

  • Brass is a soft material and wears rapidly, degrading the operational characteristics of the contact.

  • Brass oxidizes easily and thus does not perform well in wet or corrosive environments.

  • Brass's contact resistance increases rapidly due to tarnishing that occurs in normal use.
