Best rated nanocrystalline cores factory: Mumetal cores are highly specialized magnetic shielding materials that offer unparalleled performance in reducing electromagnetic interference. These cores are made from a unique alloy of nickel, iron, copper, and molybdenum, which gives them exceptional magnetic permeability and high saturation flux density. Mumetal cores are commonly used in sensitive electronic devices such as transformers, sensors, and current transformers to minimize the effects of stray magnetic fields.

Application field of nano magnetic core: Noise is the main circuit interference source in many power electronic devices. Various filter elements must be used to reduce noise. As the main component of differential mode inductance, magnetic particle core plays a key role in the filter. In order to obtain better filtering effect, the magnetic particle core material is required to have the following performance characteristics: high saturated magnetic induction, wide constant magnetic conductivity, good frequency characteristics, good AC / DC superposition characteristics and low loss characteristics. According to the above requirements, soft magnetic materials for inductance such as iron powder core, notched amorphous alloy core and iron nickel aluminum powder core (MPP powder core) have been developed successively. These materials have played their respective advantages and roles under different application conditions.
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.
Amorphous Core is preferred choice for transformers required low losses at high frequency. We have amorphous c-cores,amorphous ribbon cores,amorphous cut cores,amorphous core transformers .

There are 50% and 80% nickel iron materials available, in which we manufactures Mumetal Toroidal core and Mumetal C-core, for the applications in high quality Current Transformers and power supplies industries.
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.

As the iron core of the transformer, generally 0.35mm thick cold-rolled silicon steel sheet is selected.
