Product Material

AgNi

General Description

AgNi materials have higher resistance to arc erosion and contact welding than Ag or FAg.Both Properties are improved withincreasing Ni content. All AgNi materials show good workability and are easy to weld to contact supports. Low tendency towards material transfer in DC applications AgNi materials are environment-protective materials.

Application Scope

AgNi contact materials find a wide range of application in Low voltge switching devies. They are used in power relays,small contactors,light switches,temperature controllers etc,as well as in protective switches (in the latter case they are used in asymmetric contact pairs, for instance,against AgC or AgZnO materials).
