Bonded NdFeB Magnets

Short Description:

Bonded NdFeB, composed of Nd2Fe14B, is a synthetic magnet. Bonded NdFeB magnets are magnets made by “press molding” or “injection molding” by mixing quick-quenched NdFeB magnetic powder and binder. Bonded magnets have high dimensional accuracy, can be made into magnetic components with relatively complex shapes, and have the characteristics of one-time molding and multi-pole orientation. Bonded NdFeB has high mechanical strength, and can be formed at one time with other supporting components.
Bonded magnets appeared around the 1970s when SmCo was commercialized. The market situation of sintered permanent magnets is very good, but it is difficult to precisely process them into special shapes, and they are prone to cracking, damage, edge loss, corner loss and other problems during the processing. In addition, they are not easy to assemble, so their application is limited. To solve this problem, the permanent magnets are pulverized, mixed with plastic, and pressed into a magnetic field, which is probably the most primitive manufacturing method of bonded magnets. Bonded NdFeB magnets have been widely used due to their low cost, high dimensional accuracy, large freedom of shape, good mechanical strength, and light specific gravity, with an annual growth rate of 35%. Since the emergence of NdFeB permanent magnet powder, flexible bonded magnets have achieved rapid development due to its high magnetic properties.

Product Description








The production and application development of bonded NdFeB permanent magnet materials is relatively late, the application is not wide, and the amount is small, mainly used in office automation equipment, electrical machinery, audio-visual equipment, instrumentation, small motors and measuring machinery, in mobile , CD-ROM, DVD-ROM drive motor, hard disk spindle motor HDD, other micro DC motors and automation instruments and other fields are widely used. In recent years, the application ratio of bonded NdFeB permanent magnet materials in my country is as follows: computers account for 62%, electronics industry accounts for 7%, office automation equipment accounts for 8%, automobiles account for 7%, appliances account for 7%, and others account for 9%.
