3 min readQuality amorphous metal cores factory supplier: Amorphous cores are a versatile class of soft magnetic materials widely used in various industries. The transformer amorphous core possess a disordered atomic structure that lacks the crystalline organization found in traditional ferromagnetic materials. This unique property allows amorphous cores to exhibit exceptional magnetic characteristics such as low core loss and high saturation induction, rendering them highly desirable for numerous applications. The amorphous transformer core is suitable for use in electromagnetic components like inductors and chokes used across diverse fields ranging from aerospace and automotive industries to renewable energy systems. Find a lot more info on amorphous transformer core.
The soft magnetic particle core will still be high along the high BS in the future μ、 High Tc, low PC, magnetic powder core is a soft magnetic material made of ferromagnetic powder and insulating medium. Because the ferromagnetic particles are very small (0.55 for high frequency) μ M is separated by non-magnetic electrical insulating film material. Low HC and high frequency, miniaturization and thinness to meet the trend of increasingly thin film, miniaturization and even integration of magnetic components.
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.

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. 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.

Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel with silicon (silicon is also called silicon), and its silicon content is 0.8 ~ 4.8%. The reason why silicon steel is used as the iron core of transformer is that silicon steel itself is a magnetic material with strong magnetic conductivity. In the energized coil, it can produce large magnetic induction intensity, which can reduce the volume of transformer.
