Amorphous cores manufacturer and supplier in China: Nanocrystalline cores are advanced materials used in the construction of transformers and inductors. The nanocrystalline transformer core is made up of tiny crystalline grains, typically measuring just a few nanometers in size. The small grain structure allows for superior magnetic properties, including high permeability and low coercivity. This results in reduced core losses and improved efficiency, making nanocrystalline cores an ideal choice for high-frequency applications where minimizing energy loss is crucial. The excellent thermal stability of nanocrystalline magnetic core ensures consistent performance over a wide range of temperatures. Discover many more information on transformer core manufacturers.
At present, up powder core occupies the main share in the high-end market. However, due to the complex manufacturing process of M, that is, powder core and the noble price of raw materials, the price of powder core remains high and the scope of application is restricted to a certain extent. In recent years, iron-based nanocrystalline soft magnetic powder core has attracted much attention because of its low price, simple preparation process and excellent performance. Its research is quite active, which is expected to replace the local use of up powder core and be applied in the field of high frequency.
Fe based amorphous alloys are competing with silicon steel in power frequency and medium frequency fields. Compared with silicon steel, iron-based amorphous alloy has the following advantages and disadvantages. The saturated magnetic flux density BS of iron-based amorphous alloy is lower than that of silicon steel. The filling coefficient of Fe based amorphous alloy core is 0.84 ~ 0.86. It shows that Fe based amorphous alloy has better resistance to power waveform distortion than silicon steel.

As the iron core of the transformer, generally, 0.35mm thick cold rolled silicon steel sheet is selected. It is cut into long pieces according to the size of the required iron core, and then overlapped into “day” shape or “mouth” shape. In principle, in order to reduce eddy current, the thinner the silicon steel sheet, the narrower the spliced strip, and the better the effect. This not only reduces the eddy current loss and temperature rise, but also saves the material of silicon steel sheet. But in fact, when making silicon steel sheet iron core. Not only from the above favorable factors, because making the iron core in that way will greatly increase the working hours and reduce the effective section of the iron core. Therefore, when making transformer iron core with silicon steel sheet, we should start from the specific situation, weigh the advantages and disadvantages and choose the best size.

Since silicon steel has the above advantages, why not use the whole silicon steel as the iron core and process it into a sheet? This is because the sheet iron core can reduce another iron loss – “eddy current loss”. When the transformer works, there is alternating current in the coil, and the magnetic flux generated by it is of course alternating. This changing magnetic flux produces an induced current in the iron core. The induced current generated in the iron core flows in a ring in a plane perpendicular to the magnetic flux direction, so it is called eddy current. Eddy current losses also heat the core. In order to reduce the eddy current loss, the iron core of the transformer is stacked with silicon steel sheets insulated from each other, so that the eddy current passes through a small section in the narrow and long circuit, so as to increase the resistance on the eddy current path; At the same time, the silicon in silicon steel increases the resistivity of the material and reduces the eddy current.
