NdFeB magnet is a tetragonal crystal formed by neodymium, iron and boron (Nd2Fe14B) with extremely strong magnetism. NdFeB magnet has significant advantages over other magnets, which are mainly reflected in the following aspects:
1. Excellent magnetic properties
Strong magnetism: NdFeB magnet has extremely high magnetic properties, and its BHmax value is 5-12 times that of ferrite magnets and 3-10 times that of AlNiCo magnets. This good magnetic property enables NdFeB magnets to absorb heavy objects equivalent to hundreds of times their own weight, meeting various application requirements of high magnetic field strength.
High coercivity: NdFeB magnets also have very high coercivity, which means they are very stable and can maintain a high magnetic field strength even under extreme conditions. This stability makes NdFeB magnets perform well in applications that require high stability and reliability.
2. Good high temperature resistance
NdFeB magnets have high temperature and Curie temperature, and can maintain stable magnetism at higher temperatures. Although their original working temperature is generally around 80 degrees Celsius, the specially treated magnets can reach a higher working temperature of 200 degrees Celsius or even higher. This high temperature resistance allows NdFeB magnets to work normally in high temperature environments and meet the needs of special applications.
3. Strong corrosion resistance
Among all rare earth permanent magnets, NdFeB has high corrosion resistance (except oxidizing acids). This good corrosion resistance allows NdFeB magnets to be used in some corrosive environments, extending the service life of the magnets and reducing maintenance costs.
4. High mechanical strength and good toughness
NdFeB magnets have high mechanical strength and good toughness, and can cope with some high-intensity application environments. This feature allows NdFeB magnets to perform well in situations where they need to withstand greater mechanical stress, such as wind turbine blades.
5. Strong plasticity
NdFeB magnets can be processed into various shapes to meet different application requirements. This plasticity makes NdFeB magnets more flexible in the manufacturing process and can meet the requirements of various complex shapes and sizes.
6. Wide application fields
Due to the above advantages, NdFeB magnets are widely used in aerospace, electronics, electromechanical, instrumentation, medical and other fields. In these fields, NdFeB magnets play an irreplaceable role and promote the development and progress of related technologies.
