What is Sintered NdFeB Magnet


The chemical composition of sintered nd-FE-B Permanent magnet materials
The NdFeB Permanent magnet is a permanent magnet material based on intermetallic compound nd2fe14b. The main components are rare earth (ND), Fe (Fe) and Boron (B). In order to obtain different properties, the rare earth nd is available in partial dysprosium (dy), praseodymium (PR) and other rare earth metals, iron can also be cobalt (CO), Aluminum (AL) and other metal substitutes, boron content is small, but the formation of the quartet crystal structure intermetallic compounds play an important role, making compounds with high saturation magnetization, High uniaxial anisotropy, and high Curie temperature.

The manufacturing process of sintered nd-FE-B Permanent Magnet materials
sintered NdFeB Permanent magnets are used in the powder metallurgy process, after smelting the alloy is made into powder and pressed into the magnetic field pressure embryo, the pressure embryo in the inert gas or vacuum sintering to achieve densification, in order to improve the coercivity of magnets, usually need to carry out aging heat treatment.

sintered nd-FE-B Permanent magnet materials for the application of Sintered NdFeB permanent magnets have excellent magnetic properties, widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields, more common permanent magnet motors, speakers, magnetic separator, computer disk drives, magnetic resonance imaging equipment and other instruments.
