Ferrite cores are magnetic cores made of ferrite and are one of the main components of transformers or other wound components such as inductors. The iron core is characterized by its high magnetic permeability as well as its low electrical conductivity (to avoid eddy currents). Ferrite cores are widely used in electronic devices, communication equipment, etc.

The primary role of ferrite cores is as magnetic components in electronic devices to manage and regulate electrical current. By winding the coil on the magnetic core, it can easily generate magnetic flux and offset the influence of current on passive components, so that the entire electronic components can achieve greater stability. At the same time, ferrite cores can also be used in a variety of electronic equipment, such as frequency controllers, transformers, filters, etc.
Ferrite cores have the following main features:
1. High stability. The magnetic permeability of the ferrite core is basically not affected by temperature, time and external signal sources, and can achieve long-term high-efficiency operation.
2. Low loss. Since the ferrite material has very good magnetic saturation characteristics, the loss of the ferrite core is smaller than that of other materials.
3. High saturation magnetic induction. The saturation magnetic induction of ferrite material is very high, so the number of turns can be reduced when making a transformer, thereby reducing the volume and weight.
4. Good corrosion resistance and wear resistance. Ferrite material has good corrosion resistance and wear resistance, and can be used in harsh environments.
"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
