Amorphous metal cores factory right now: 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. Read many more information on amorphous metal cores.
On the one hand, it can isolate eddy current, and the data is suitable for higher frequencies; On the other hand, due to the gap effect between particles, the data has low permeability and constant permeability; Because the particle size is small, there is basically no skin phenomenon, and the change of permeability with frequency is relatively stable; Moreover, the powder core can be prepared into special-shaped parts of various shapes for different fields; Finally, the damaged strip in industry can be crushed into magnetic powder, and then made into magnetic powder core, which can reduce the loss and improve the use value of data. The magnetoelectric properties of magnetic particle core mainly depend on the permeability of powder material, size and shape of powder, filling coefficient, content of insulating medium, forming pressure and heat treatment process.
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.
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.

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.
