Amorphous cores manufacturer and supplier from TRANSMART: 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. See many more details at nanocrystalline transformer core.
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.
However, at the same BM, the loss of Fe based amorphous alloy is smaller than that of 0.23mm thick 3% silicon steel. It is generally believed that the reason for low loss is the thin thickness and high resistivity of iron-based amorphous alloy strip. This is only one aspect. The main reason is that the iron-based amorphous alloy is amorphous, the atomic arrangement is random, there is no magnetocrystalline anisotropy caused by atomic directional arrangement, and there is no grain boundary causing local deformation and composition offset. Therefore, the energy barrier hindering domain wall motion and magnetic moment rotation is very small, with unprecedented soft magnetism, so it has high permeability, low coercivity and low loss.

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.
