Metal Core of Electronic Transformer

Electronic transformer is usually made of soft magnetic ferrite now, and the uniformity of ferrite produced in China is not very good. So, ferrite is mainly imported from other countries, but some disadvantages occur, such as high price, large volume and big temperature rise, etc. On the other hand, our metal core of electronic transformer differs from the traditional product. It is made of nanocrystalline core via special annealing technique, and the volume is reduced greatly. Its performance is superior to ferrite in many aspects, and it is the perfect product for electronic transformer manufacturers.

Electronic transformer is composed of core and winding, and we can supply metal core of electronic transformer with different specifications. Our product gains outstanding comprehensive magnetic properties, and it has low core loss as well as high permeability. The saturation magnetic flux density is as high as 1.25T, and it can keep stable magnetic property if the temperature isn't over 570℃ which means good temperature stability is obtained. This metal core combines the advantages of silicon steel, permalloy and ferrite together, and is becoming the optimum choice for inverter transformer, especially for high frequency big power main transformer.

Huaxin is a professional metal core of electronic transformer manufacturer and supplier in China. We provide a variety of products, including switching power supply magnetic core, electricity meter current transformer, permalloy strip of magnetic core, and more.
