Soft Magnetic Materials Nanocrystalline Alloy Jan 26,2022

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.

According 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:
