1  Introduction

 

Composed of Fe, Si, B, Nb, Cu etc. Iron based amorphous alloy including Cu and Nb element can be formed into crystallite with size in 10-20nm above crystallization temperation through particular annealing treatment. The crystallite material is defined as nanocrystalline alloy.  

 

2  Application

 

EMC common mode and differential mode filter inductor core;

switching-mode power supply transformer core;

current mutual sensor core (zero sequence, leakage protection);

Magnetic amplifier, spike killer core, saturable inductor core;

 

3  Feature

 

High saturation flux density, high permeability, low coercivity, Low loss, good stability, high strength and corrosion resistance, can replace silicon steel, permalloy and ferrite as ideal material for transformer, mutual inductor, its components, has the highest PQ ratio.
