Description

Bonded NdFeB arc magnet is mainly produced by molding compression of the NdFeB compound alloy powder with epoxy resin, and then shaped into a arc with molds,with the following characteristics:


1、Higher magnetic property: the magnetic property of Bonded NdFeB arc magnet is between that of sintered magnet and ferrite, with good consistency and stability;


2、High precision and freeness of Bonded NdFeB arc magnet shape: the magnet shape and dimension can be guaranteed by the tooling, like ring, segment, block, etc., without further sintering and machining;


3、Good corrosion resistance of Bonded NdFeB arc magnet: after Epoxy coating or special surface treatment, the magnet can be applied under normal or unfavorable environment conditions in a durable period;


4、Diverse magnetization of Bonded NdFeB arc magnet: multi-pole, skew and radial magnetization can be available. The magnetic surface can be on the ID, OD and end surface or combined magnetization. The field distribution can be square, sinusoid, etc.


Bonded NdFeB arc magnet can be applied on all kinds of small and micro-motors, such as spindle motor, stepping motor, synchronous motor, DC motor and brushless DC motor, and it can also be used for sorts of sensors. It can replace some sintered NdFeB magnet and Ferrite, making motor assembling easier and more reliable, reducing cost and improving efficiency.


Our Bonded NdFeB arc magnets are all REACH and ROHS compliant and don’t contain any SVHC. It is produced according to ISO 9001 and ISO 14001 Quality Control Standards. PPAP, APQP, CPK/PPK, 8-D, CO, FTA are available. If you require a bespoke bonded NdFeB magnets or magnetic assembly, Technical Support or our bonded NdFeB Magnet Technical Data Sheet, please contact us. If you need a quotation for an existing magnet shape or a bespoke shape, please contact us. We offer a highly competitive price for your reference.

Yanhe Magtech® is familiar with information of magnet industry in China. We have long-term strategic cooperative relations with the other six factories. Two are for sintered NdFeB, two are for Hard Ferrite, and two are for AlNiCo and SmCo. Therefore, Yanhe Magtech® can provide accurate information and the first-class high-quality products with the most competitive price for our customers.


Yanhe Magtech® has passed the authentication of ISO 9001:2015, and has covered Product-liability insurance. We eliminate the customers’worries completely. With the reliable quality, our products are exported to Europe, the United States and Asia, etc.


Yanhe Magtech® aim: To provide more extensive information, products, technology design and service for customers. To make customers satisfied in the course of commercial activity.
