Nanocrystalline cores manufacturer and supplier in China: Transmart is a transformer core manufacturer with years of experience, mainly providing nanocrystalline cores, amorphous cores, silicon steel cores, common mode chokes, etc. We specialized in a broad range of tape wound cores in amorphous metal materials, nanocrystalline alloys, silicon electrical steels, and mu metal nickel alloys for a wide variety of applications including solar inverters, home appliance, audio system, etc. Nanocrystalline Ribbons are thin strips of material that have been engineered at the nanoscale to possess unique properties and characteristics. These ribbons are typically made up of highly ordered crystalline structures with grain sizes on the order of a few nanometers, giving them exceptional strength and durability.

At present, up powder core occupies the main share in the high-end market. However, due to the complex manufacturing process of M, that is, powder core and the noble price of raw materials, the price of powder core remains high and the scope of application is restricted to a certain extent. In recent years, iron-based nanocrystalline soft magnetic powder core has attracted much attention because of its low price, simple preparation process and excellent performance. Its research is quite active, which is expected to replace the local use of up powder core and be applied in the field of high frequency.
Amorphous nanocrystalline alloys are competing with soft ferrite in the field of medium and high frequency. In 10kHz to 50KHz electronic transformer, the working magnetic flux density of iron-based nanocrystalline alloy can reach 0.5T and the loss P0.05 5 / 20K ≤ 25W / kg, so it has obvious advantages in high-power electronic transformer. In 50 kHz to 100 kHz electronic transformer, the loss of iron-based nanocrystalline alloy is P0.05 2 / 100k is 30 ~ 75W / kg, Fe based amorphous alloy P0.05 2 / 100k is 30W / kg, which can replace some ferrite markets.

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.
