NdFeB magnet is a tetragonal crystal formed by neodymium, iron and boron, also known as NdFeB magnet. The magnetic energy product of this magnet is greater than that of samarium cobalt magnet, which was the material with the largest magnetic energy product in the world at that time. It is usually silver in color, shiny and opaque, and can be widely used in electronic products such as hard disks, mobile phones, headphones and battery-powered tools.

In order to avoid corrosion damage, it is necessary to protect the surface of the permanent magnetic material during use, such as electroplating with gold and tin, and spraying epoxy resin on the surface.

NdFeB magnets are widely used in many fields:

Electronic computers and communication equipment: As a heat dissipation material for the CPU, it can greatly reduce the operating temperature and thus extend the service life.

Hard disk drive: High-performance permanent magnetic materials are required in hard disks to power and maintain data storage. NdFeB magnets, as the main component of rare earth permanent magnetic materials in the magnetic head, ensure the reliability and safe transmission of data.

Electric vehicles: Electric vehicles have high requirements for lightweight and energy density. The use of NdFeB magnets in permanent magnet synchronous motors improves the overall performance of electric vehicles and reduces the cost of use.

Wind power generation: With the development of new energy, wind power generation has become an increasingly important source of energy. The application of NdFeB magnets in direct-drive permanent magnet wind turbines has improved power generation efficiency and reliability.

Medical equipment: The medical field has extremely high requirements for fine, stable and reliable equipment. For example, magnetic resonance imaging (MRI) requires high-performance permanent magnetic materials to generate a stable magnetic field.

Consumer electronics: Many consumer electronics products, such as smartphones, tablets, wearable devices, etc., require high-performance magnets in audio, motor and other components.

Aerospace: The aerospace field has extremely high requirements for lightweight and performance of components. NdFeB magnets play a very critical role in magnetic levitation, high-speed rotation and other scenarios.
