For the modern electronic technology field, as a high performance soft magnetic material, the nanocrystalline core are gradually becoming an indispensable core components in various of electronic devices. Thanks for its unique structure and excellent magnetic properties, it plays an more and more important role in application of power electronics, communications, new energy, etc. Here let's deep seek into the nanocrystalline cores' characteristics, application scenarios, and future development trends.

What’s NANOCRYSTALLINE CORE?

The nanocrystalline core is a soft magnetic material which composed of nanoscale grains, with grain sizes typically ranging from 10~100 nanometre.  Usually nanocrystalline cores preparation through adopts rapid solidification technology, such as melt spinning quenching method, cooling the molten metal to form an amorphous strips, and then subjecting it to appropriate heat treatment, uniformly distributed nanocrystals in the materials. Such production skills guarantee the nanocrystalline has dual structural characteristics of amorphous and nanocrystalline. Its special micro-structures make the core with excellent magnetic properties, such as high permeability, low loss, and good temperature stability.

The key properties of NANOCRYSTALLINE CORE

High permeability & low core loss

Comparing to Silicon Steel  and ferrite materials, nanocrystalline core magnetic core loss are much lower. The nanocrystalline core with extremely high initial permeability and Maximum magnetic permeability. Such Characteristic makes it significantly improving energy conversion efficiency, particularly outstanding performance in high frequency circuits.

Broadband characteristics

The nanocrystalline core's magnetic permeability could remain stable over a wide frequency range, which excellent performance for use in high frequency transformers, inductors and other devices. This broadband characteristic makes it widely used in the communication and power electronics field.

Excellent temperature stability

The nanocrystalline core's curie temperature is much higher than that of traditional materials, they can still maintain good magnetic properties in high temperature environments, making them very suitable for application in high-temperature scenarios such as new energy vehicles and photovoltaic inverters.
