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.
