Introduction to performance characteristics of permalloy core:

Permalloy metal magnetic core: various permalloy materials have their own characteristics. Compared with silicon steel and ferrite, they have excellent typical magnetic properties and high temperature stability and aging stability High initial permeability permalloy (iu79, ij85ij86) iron core is often used to make current transformer and small signal transformer; High rectangular permalloy like material (iu51) iron core is often used to make magnetic amplifier and two-stage pulse transformer; Low remanence permalloy (ij67h) iron core is often used to make medium and small power unipolar pulse transformer.

Permalloy magnetic core is mainly used for power collection, energy conversion, power measurement, leakage protection, etc. For example, various types and different levels of current transformers, power transformers, current sensors, etc. used in the power system. It has superior magnetic properties, the highest permeability in weak magnetic field, low saturation magnetic induction and high resistivity, and good consistency. It has a wide range of applications.
