As new developed materials, nanocrystalline and amorphous cores have the advantage of high permeability and low hysteresis loss. We can provide cores of wide-range dimensions which can serve as important components for different electrical devices and instruments.
Due to the high initial permeability, the nanocrystalline cores can be used for electric current measurement, such as miniature current transformers of high accuracy class and so on. We can also provide nanocrystalline cores for power systems, high power switch and control, etc.
As we can treat the nanocrystalline cores by different annealing processes, with or without external magnetic field, we can get adjustable Br/Bs ratio. So, our nanocrystalline cores are very suitable for switched-mode power supplies, EMC common mode chokes, and so on.
Our fe-based amorphous cores have saturation induction as high as 1.56T, while the iron loss is very low. So, it can replace conventional silicon steel cores for voltage transformers and current transformers and save a lot of energy.
We can also combine a amorphous core together with a nanocrystalline core, which can serve as DC immune CT dual core. Such kind of core is very useful, as it can work properly in circuit where DC offsets also exist. These cores can be used for our DC immune current transformers we made ourselves.
The normal shape of our cores is toroidal or ring type, as the flux leakage is nearly none. But we can also provide special shape cores or non-toroidal cores, like rectangular or oval nanocrystalline cores and so on. Split cores or cut C cores are also available for some applications of transformers or inductors where air gap is required.
