Silver-Nickel Contact Material
Silver-Nickel Contact Tip
(85% Ag and 15% Ni)
Close-up of Silver-Nickel Contact Tip
We use solid silver-nickel contact surfaces on almost all of our plugs and receptacles. The contacts’ 85% silver and 15% nickel composition combines the durability of nickel with the excellent conducting properties of silver.
Silver-nickel contacts provide significant advantages over the brass materials used on most other types of plugs and receptacles:
- 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 well in and withstands wet and corrosive environments.
The combination of the silver-nickel material with spring-loaded butt-style design makes the contacts ideal for repetitive making and breaking of connections under load.
