Sintered NdFeB magnets are the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 26 MGOe to 52 MGOe. Nd-Fe-B is the third generation of permanent magnet developed in the 1980s. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes. With its excellent magnetic characteristics, abundant raw material and relatively low prices, Nd-Fe-B offers more flexibility in designing of new or replace the traditional magnet materials such as ceramic, Alnico and Sm-Co to achieve high efficiency, low cost and more compact devices.
Magnetic Properties of Sintered NdFeB Magnets
1.Licensed Products by SSMC-MQ - ISO 9002 Quality Standard Certified
2.The above-mentioned data of magnetic parameters and physical properties are given at room temperature.
3.The maximum service temperature of magnet is changeable due to the ratio length and diameter and environmental factors.
4.Special properties can be achieved with custom method.
