Rare earth permanent magnet material ( iron boron ND2FE14B) is divided into the following three types according to different production processes:

(1) Bonding （b （(Bonded NDFEB)

Plug -in iron boron is a composite cymbal iron boron permanent magnet with a composite cymbal iron boron -boron permanent mixing with adhesives such as resin, plastic or low melting point metal, and then using compression, squeezing or injection molding. The product is formed first, and there is no need to make a secondary processing, which can be directly made into various complex shapes. Each direction of bonding the iron boron is magnetic, and it can be processed into iron boron compressed molds and injection molding molds. High precision, excellent magnetic properties, good corrosion resistance, and good temperature stability.

(2) Sintened NDFEB

The sintering iron boron permanent magnet is smelted after being grinded by the airflow. The stubborn power is very high and has a high magnetic performance. Its maximum magnetic energy accumulation (BHMAX) high iron oxygen (Ferrite) is more than 10 times. Its mechanical properties are also quite good, and they can cut different shapes and drilling. The maximum operating temperature of high -performance products can reach 200 ° C.

Because its material content is easy to cause rust, different coating treatment must be performed on the surface according to different requirements. (Such as galvanized, nickel, environmentally friendly zinc, environmental protection nickel, nickel copper, nickel, nickel, nickel, copper -nickel, etc.). Very hard and crispy, high -resistant degenerative, high cost/performance ratio, not suitable for high work temperature (> 200 ° C).

(3) injection molding （iron boron (zhusu ndfeb)

There are extremely high accuracy and easy to make thin -walled ring or thin magnetic shapes with complicated heterosexual shapes.
