Nanocrystalline cores wholesale provider 2024: 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. Discover extra information on nanocrystalline cores.

After surface insulation treatment, the magnetic core is evenly mixed with the binder, pressed and annealed. There are basically three ways to obtain nanocrystalline powder: amorphous strip crushing after annealing and crystallization, mechanical alloying and molten alloy atomization. At present, mechanical alloying is still in the laboratory research stage. A few companies produce amorphous strip crystallization in small quantities in China, but it is unable to expand the market due to cost reasons. Compared with other methods, molten alloy atomization method has high efficiency and low cost. Its disadvantage is that the amorphous content of the powder is low and the loss is high.

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.

The common mode inductor using nanocrystalline core material can well suppress the peak voltage, protect sensitive components, and reduce the motor shaft voltage. Because of the unique characteristics of nanocrystalline core, it has been well used in some high-power system industries. Electric energy meter, power meter, ammeter, electric measuring equipment and other instrument fields. Various power current transformers in power transmission and distribution monitoring system. Leakage protection, relay protection, servo motor protection, fire monitoring, etc Current and voltage data sampling, etc. Discover even more details at https://www.transmartcore.com/.

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.
