Premium amorphous cores manufacturer and supplier: Nanocrystalline soft magnetic materials are a class of advanced materials that have garnered significant attention in recent years due to their unique properties and potential applications. These materials consist of nanoscale grains, typically ranging from a few to several tens of nanometers in size, which results in an ultrafine microstructure. This fine grain structure allows for improved magnetic properties such as high permeability, low coercivity, and low core losses compared to conventional soft magnetic materials. The enhanced performance of nanocrystalline soft magnetic materials makes them highly suitable for various technological applications, including power electronics, transformers, sensors, and electromagnetic shielding. Such as：Nanocrystalline Ribbons. See additional details at https://www.transmartcore.com/.
Nanocrystalline magnetic core is a new type of soft magnetic material with high BS, high effective permeability, high DC bias stability, high temperature stability, wide frequency adaptability, low power consumption and low cost. It is applied to high-power, high-frequency, miniaturized and high conversion switching power transformer and choke. At present, the solar energy industry inverter, water energy, air energy, electric energy conversion and charging of hybrid vehicles have great market space and future, because the performance of nanocrystalline magnetic core is highly controllable.
It is worth noting that Japan is vigorously developing FEMB amorphous alloy and nanocrystalline alloy. Its BS can reach 1.7 ~ 1.8T, and the loss is less than 50% of the existing FeSiB Amorphous Alloy. If it is used in power frequency electronic transformer, the working magnetic flux density can reach more than 1.5T, while the loss is only 10% ~ 15% of silicon steel power frequency transformer, it will be a more powerful competitor of silicon steel power frequency transformer. Japan is expected to successfully trial produce FEMB amorphous alloy power frequency transformer and put it into production in 2005.

We know that the actual transformer always works in AC state, and the power loss is not only on the resistance of the coil, but also in the iron core magnetized by alternating current. Usually, the power loss in the iron core is called “iron loss”. The iron loss is caused by two reasons, one is “hysteresis loss” and the other is “eddy current loss”. Nanocrystalline magnetic core is a small part with magnetic conductivity. There are nanocrystalline particles with small particles in the center of nanocrystalline magnetic core. The working principle of nanocrystalline magnetic core is to absorb the common mode current in the cable through the principle of induction heating and convert it into heat to dissipate. 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.
