Find Meltric Plugs with Silver-Nickel Contacts
Silver-Nickel Contact Tip
(85% Ag / 15% Ni)
Looking for plugs with silver-nickel contacts? Meltric uses a solid 85% silver / 15% nickel composition across nearly all product lines, combining high conductivity with exceptional wear resistance.
This material delivers 20 times the conductivity of the brass found in competing plugs and receptacles, resulting in lower contact resistance and longer service life.
- 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.
Closeup of Silver-Nickel Contact Tip
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
- 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.
In an oxidized state, silver-nickel is 20 times more conductive than brass
