Orientation and Magnetization of Sintered NdFeB Magnets
Magnetic materials are divided into two categories: isotropic magnets and anisotropic magnets:
Isotropic magnets have the same magnetic properties in any direction and can be magnetized arbitrarily;
Anisotropic magnets have different magnetic properties in different directions, and the direction in which the best magnetic properties can be obtained is called the orientation direction of the magnet.
Common anisotropic magnets are mainly hard magnetic materials such as radially sintered ndfeb magnets and sintered SmCo.
Propiedades físicas de los imanes de NdFeB sinterizados
As the core functional component, sintered magnet production permanent magnets are widely used in instruments and equipment such as motors, electroacoustics, magnets and sensors. During the service process, the magnet will be subjected to environmental factors such as mechanical force, cold and heat changes, and alternating electromagnetic field. If environmental failure occurs, it will seriously affect the function of the equipment and cause huge losses. Therefore, in addition to the magnetic performance index, we also need to pay attention to the mechanical, thermal and electrical properties of the magnet, which will help us better design and use the magnetic steel, and is of great significance for improving the stability and reliability of its service. .
Métodos habituales de tratamiento del NdFeB sinterizado
The main shapes of sintered NdFeB magnets include square pieces, cylinders, rings, tiles, sectors and various special-shaped products. In actual production, large blanks are produced first, and then obtained through post-processing according to the size requirements of users. The final ndfeb magnet strength.
¿Qué sabes de los imanes?
La composición del superimán: hierro, cobalto, níquel y otros átomos, la estructura interna del átomo es relativamente especial, y tiene un momento magnético. Los imanes pueden generar campos magnéticos y tienen las características de atraer sustancias ferromagnéticas como el hierro, el níquel, el cobalto y otros metales
¿Para qué sirve un imán de neodimio?
ventajas de los imanes de neodimio que son imanes permanentes artificiales con la fórmula química NdFeB, son imanes de neodimio hierro boro. Este tipo de imán, que es también el imán de tierras raras más utilizado, es un imán permanente cuyo magnetismo sólo es superado por el de un imán de holmio con un campo magnético de cero grados absolutos. Los imanes permanentes de neodimio se utilizan con frecuencia en aparatos eléctricos. Esta sustancia tiene las propiedades magnéticas más fuertes hasta la fecha, lo que le ha valido el apodo de "rey de los imanes".
