Introduce:
Fe-based Nanocrystalline alloy strip has the properties of high Saturation magnetization and
permeability, low coercive force and core loss, good stabilities on temperature and time effect,
excellent abilities of anti-wearing and anti-rusty, and it shows the best property-value ratio
among all of the soft magnetic materials.
Fe-based Nanocrystalline Ribbons can be utilized to supplant silicon steel, Permalloy, and
ferrite as brilliant materials to make transformer centers for high-recurrence switch mode control
supplies.
Nano crystalline cores are Iron Based cores which is an uncommonly grown delicate attractive
material with low magneto striction, high penetrability immersion transition thickness of 1.25t and
working temperature of 120 degrees celsius or more. Nanocrystalline cores are accessible in
type of toroidal or stadium formed tape-wound centers. The material itself is fragile and requires
an insurance against mechanical powers, which is either given by plastic core boxes or a reasonable
warmth resistive covering. Once covered or boxed, the centers are amazingly hearty and the major
attractive properties are highly linear and not very much dependent from temperature.
Application:
The Fe-based nanocrystalline ribbons can replace silicon steel, permalloy and ferrite cores of
main transformers,control transformers, filter inductors, energy storage inductors, reactors,
magnetic amplifiers of various forms of high-frequency (20kHz-100kHz) switching power
supplies. And the magnetic core of saturable reactor, EMC filter common mode chokes and
differential mode chokes, ISDN miniature isolation transformer, also widely used in various
types of transformer cores with different accuracy.
EMC common mode, normal mode filter chokes
• Cores for main transformer of switch power supply and control transformer
• Different accuracy CT /VT cores
• Mag-amp and pulse killer cores
Characteristics:
High saturation magnetic induction strength, high magnetic permeability,Low coercive force, Low
core loss and high temperature stability, wear resistant and corrosion resistant, at the same time
has a lower cost, among all the soft magnetic materials it is most cost effective.
