High Power Transformer Core

Compared with other soft magnetic materials, our high power transformer core owns better properties, and it is the ideal material for transformers. Our product features low coercivity, low core loss, high Curie temperature and saturation magnetic flux density, and it can cut down the volume of transformer as well. In addition, the best application frequency ranges are within 15kHz for amorphous material, and 15kHz-50kHz for nanocrystalline. This core is suitable for many kinds of transformers, such as pulse type, electronic type, distribution type, inverter welding machine type, high-frequency switching power supply type, high and medium frequency big-power type and others.
