Nanocrystalline cores feature very high permeability over wide frequency. They are very suitable for common mode choke to be used as EMC filter to compress conducted common mode noise. Compared to traditional ferrite core, nanocrystalline core has a lot of advantages as high inductance, good filter effective, small size and volume, less turns of copper wire, lower power consumption and high efficiency. Permeability of our nanocrystalline core can reach 20000, we are at the leading position.Curie temperature of nanocrystalline core is about 560℃, much higher than traditional ferrite core about 200℃. High curie temperature make nanocrystalline core excellent thermal stability, and can continuous working at up to 120℃ environment.

Amorphous alloys have the similar characteristics of glass structure, which not only make them have excellent mechanical properties, physical properties and chemical properties, but more importantly, the new technology of producing amorphous alloys using this rapid quenching method is less than the cold-rolled silicon steel sheet process. 6 to 8 processes can save energy consumption by 60% to 80%, which is an energy-saving, time-saving and efficient metallurgical method. Moreover, the amorphous alloy has low coercivity and high magnetic permeability, and its core loss is significantly lower than that of oriented cold-rolled silicon steel sheet, and its no-load loss can be reduced by about 75%. Therefore, the use of amorphous alloys instead of silicon steel sheets to manufacture transformer cores is one of the main means to save energy and reduce consumption in today’s power grid equipment.
