Amorphous metal cores wholesale manufacturer and supplier with TRANSMART: 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. Read many more information on amorphous cores.
Characteristics and application of nanocrystalline magnetic core: High permeability, nanocrystalline Fe73 5Cu1Nb3Si13. 5B9 alloy has high saturation magnetic induction. The material becomes brittle after heat treatment and is easy to be processed into alloy powder. Compared with the nanocrystalline magnetic core wound with strip, the magnetic permeability of the nanocrystalline magnetic core is still very low and the soft magnetic properties are unstable. At present, the urgent problems to be solved are as follows: 1. Effectively control the growth of nanocrystals during heat treatment; 2. Molding of magnetic particle core; 3 Effect of heat treatment specification on soft magnetic properties of magnetic particle core.
Now, the test of magnetic core material loss of power frequency power transformer is carried out under sine wave voltage with distortion less than 2%. The actual power frequency power grid distortion is 5%. In this case, the loss of iron-based amorphous alloy increases to 106% and that of silicon steel increases to 123%. If the high-order harmonic is large and the distortion is 75% (such as power frequency rectifier transformer), the loss of iron-based amorphous alloy increases to 160% and the loss of silicon steel increases to more than 300%.
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.
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.

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”.
