Nifer®50

GENERAL INFORMATION

Alloy Nifer®50 – is a magneto-soft iron-nickel alloy with the content of nickel 48%, saturation magnetic induction is 1,55 T and alloys with similar high saturation induction. Nifer®50 has the highest saturation induction, possible for similar alloys. Typical scopes: low-frequency power sensor, rotor and stator plates, throttles, high-purity relays, integrated current transformers for protective switches, stepper motors, magnetic gates, shielding. Nifer®50 it can be produced in three options depending on a scope.

 It is possible to receive the specified magnetic properties only after special final annealing. Temperature condition of annealing is set in limits 1050оС and 1250оС. After final annealing cooling is carried out to 450оС in furnaces during 5-70 hours. Further cooling isn't critical. After final heat treatment, details shouldn't be loaded mechanically as each plastic transformation leads to loss of magnetic properties
