SOFT MAGNETIC IRON NICKEL ALLOYS

Nickel is renowned for its good ductility and electrical conductivity. It has many fields of application:

  • As additional layer for a thermostatic bimetal to obtain a particular resistance
  • As additional layer for 1 and 2 Euro coins for authentication in vending machines
  • As cladding material for various coins
  • As soldering lug for batteries
  • As connecting strip for batteries
  • As various automotive components (e.g. car headlamp dippers)
  • As electrolytic anodes in for electroplating
  • As connectors in steam irons
  • As outer cap for transistors

Soft-magnetic strip is produced in FeNi alloys with a Ni content between 35 – 81%. The alloy Normaperm (35-40%) exhibits a particular increase in permeability in magnetic field strengths up to approx. 100 mOe. The alloys with 45-55% Ni have relatively high initial permeability and high induction saturation. The alloys with 76-81% Ni have high initial permeability values.
