Soft Magnetic Materials Nanocrystalline Alloy

  • March 17. 2021

Guangzhou Amorphous Electronic Technology Co.,ltd use soft magnetic materials high permeability nanocrstalline strips for cores and current transformer production. Following information about nanocrystalline alloy:


  • On the basis of the Fe-Si-B alloy composition, extral added with a trace amount of elements Cu, Nb, and prepared the amorphous ribbon by rapid solidification with a cooling rate of about 106/sec.
  • Then, amorphous ribbon is heat treated above the crystallization temperature to form a nanocrystalline alloy having a grain size of 10-20 nm.
  • Nanocrystalline alloys have more excellent magnetic properties.

Accoring to final nanocrystalline cores & current transformers electronic parameter request, the nanocryatalline alloy could be treated with transverse magnetic field processing or longitudinal magnetic field processing.


The specific DC B-H Loop with / without heat treated is shown as below:
