Permanent magnet

GTEK was established in Ningbo, China, which is the world's largest origin of rare earth raw materials for magnets. We offer the quality permanent magnets at a lower price, thanks to our state-of-the-art equipment, we offer highly customized products.

NdFeB Magnets

As a rare earth permanent magnet material, NdFeB has extremely high magnetic energy product, coercive force and energy density, and good mechanical properties. It is the strongest permanent magnet in contemporary magnetic materials.

AlNiCo Magnets

Alnico Magnet is the oldest type of magnetic steel (is called natural magnet), but its excellent adaptability to high temperature makes it still one of the most important magnetic steels.

Ferrite Magnets

Ferrite Magnets aka Ceramic Magnets, which is the small black magnet we usually see. Ferrite magnets are mainly formed of Fe2O3, BaCO3 or SrCO3 metal powder.

Samarium Cobalt Magnets

Samarium Cobalt Magnets are widely used in aerospace, defense military, microwave devices, communications, medical equipment, motors, instruments, various magnetic transmission devices, sensors, magnetic processors, magnetic cranes and other fields.

Flexible Magnets

Flexible Magnets can be easily processed into strips, rolls, sheets and other complex shapes. Due to its stable performance, good flexibility, temperature resistance and corrosion resistance, etc. it has been made into various products.


Permanent magnets can be natural products, also known as natural magnets, or can be artificially manufactured (the strongest magnets are neodymium magnets). It has a wide hysteresis loop, high coercivity, and high remanence. The permanent magnet material can maintain constant magnetic properties once magnetized.

Permanent magnets are also known as hard magnets. In the application, the permanent magnet works in the second quadrant demagnetization part of the magnetic loop after deep magnetic saturation and magnetization. The permanent magnet should have the highest possible coercive force Hc, residual magnetism Br and maximum magnetic energy product (BH) m to ensure the storage of maximum magnetic energy and stable magnetic properties.


Permanent magnets are widely used in various fields: electronics, electrical, mechanical, transportation, medical and daily necessities.

Such as the permanent magnets of:

  • speakers and telephone receivers;
  • the magnetic system of magnetoelectric meters;
  • the magnetic poles in generators and permanent magnet motors;
  • the permanent magnetic devices used in machine manufacturing (such as the permanent magnetic chucks of surface grinders, etc.) as well as the magnetic levitation system and magnetic bearings ;
  • Magnetic separation system, magnetic beneficiation, magnetic water purification system, magnetron, magnetic system of proton accelerator, etc.
