Definitions

  • the invention relates to the use of a sintered material, which consists of 80 to 100% nickel and 0 to 20% palladium, as a material for electrical relay contacts.
  • the object of the invention is to find a contact material for electrical relay contacts based on palladium-nickel, which, with a lower proportion of the expensive palladium compared to the known palladium-nickel alloys, has a high hardness and practically no increase in contact resistance under current loads shows practically no material migration for the aforementioned purpose.
  • This object is achieved according to the invention by using a sintered material which consists of 80 to 100% nickel and 0 to 20% palladium.
  • palladium-copper and palladium-silver alloys have been used as palladium alloys with a low material migration for relay contacts, although US Pat. No. 1,832,307 palladium-nickel alloys with a maximum of 70% nickel were known as possible contact materials .
  • Examples of particularly advantageous palladium-nickel sintered materials have been found to be compositions of 20% palladium and 80% nickel, 10% palladium and 90% nickel and 5% palladium and 95% nickel. Surprisingly, it has also been shown that the palladium can be completely replaced by nickel at correspondingly higher loads.
