Fe-based Amorphous strip/ribbon(1k101)

Introduction: 

 

The model of amorphous metal strip is FeCuNbSiB which is equal to international model of 1k107. Our product has ultra fine grain structure with grain size of 10mm-20mm. 

 

Advantages:

 

It has a series of advantages of high saturated magnetic induction density, high permeability, low coercive force and low iron loss, low exciting current, excellent temperature stability and cheap price etc.

 

 Application:

 

Transformer cores for high frequency switch mode power supplies

Current transformer cores for electric industry

Transformer cores for ground-fault-interrupters

Cores for filters, storage inductors, and reactors

EMC common mode chokes

Sensor cores

Cores for saturable reactors, magnetic amplifiers, beads, and pulse compressors
