Nanocrystalline transformer core manufacturer and supplier right now

Nanocrystalline transformer core manufacturer in China: Nanocrystalline cores are advanced materials used in the construction of transformers and inductors. The nanocrystalline transformer core is made up of tiny crystalline grains, typically measuring just a few nanometers in size. The small grain structure allows for superior magnetic properties, including high permeability and low coercivity. This results in reduced core losses and improved efficiency, making nanocrystalline cores an ideal choice for high-frequency applications where minimizing energy loss is crucial. The excellent thermal stability of nanocrystalline magnetic core ensures consistent performance over a wide range of temperatures. Read extra details at transformer core manufacturers.

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.

It is worth noting that Japan is vigorously developing FEMB amorphous alloy and nanocrystalline alloy. Its BS can reach 1.7 ~ 1.8T, and the loss is less than 50% of the existing FeSiB Amorphous Alloy. If it is used in power frequency electronic transformer, the working magnetic flux density can reach more than 1.5T, while the loss is only 10% ~ 15% of silicon steel power frequency transformer, it will be a more powerful competitor of silicon steel power frequency transformer. Japan is expected to successfully trial produce FEMB amorphous alloy power frequency transformer and put it into production in 2005.

Silicon steel is a traditional magnetic material mainly for 50Hz to 1000Hz electronic and electrical applications. The toroidal core is one of the main products of Transmart Industrial. Our silicon steel core series has many styles to meet the diversified needs of customers. We manufacture various type of cores in silicon steels, such as Current Sensor Cores, silicon steel transformer core, Instrument Transformer Cores, Torodal cores, C-cores, Unicore etc. Transmart Industrial carries out strict quality monitoring and cost control on each production link of toroidal core, from raw material purchase, production and processing and finished product delivery to packaging and transportation. This effectively ensures the product has better quality and more favorable price than other products in the industry.

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.

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”. Hysteresis loss is the iron loss caused by the hysteresis phenomenon in the magnetization process of the iron core. The size of this loss is directly proportional to the area surrounded by the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of transformer core made of silicon steel is small, which can greatly reduce its heating degree.
