Nanocrystalline Ribbon and Core
Nanocrystalline Ribbon and Core
The Fe-based nanocrystalline ribbon is produced by ultra-rapid solidification technology from molten steel with a cooling rate of about 106 m/s. Compared with traditional materials, it has high magnetic permeability and low loss, and is an excellent soft magnetic material. It can replace ferrites as a common mode choke, electronic transformer, etc., which can greatly improve the efficiency of the transformer, reduce the size, reduce the loss, and reduce the costs. It can also be applied to emerging fields such as automotive electronics and wireless charging. The company is the first domestic company to achieve mass production of ribbon thickness of 14μm.

Application of Nanocrystalline Core

Nanocrystalline core is made of nanocrystalline ribbon through winding, annealing, impregnation and cutting. Common mode choke, current transformers and other products made from nanocrystalline cores are mainly used in household appliances, consumer electronics, photovoltaic inverters, new energy vehicles, smart power grids and other fields.
