Introduction of bonded Nd-Fe-B magnets;
The magnetic properties of bonded NdFeB are lower than those of sintered NdFeB, but it can be manufactured into magnets with high precision and complex shape. The bonded Nd-Fe-B raw material is made by mixing rare earth magnetic powder with resin, and then is compressed and formed by press without magnetic field arrangement. Therefore, the direction of magnetic force is unrestricted. It can be used to make multi-polar magnetization, such as inner diameter, outer diameter, upper and lower, according to the design requirements. It is an indispensable magnetic element for superior products such as light, short and so on. One. In order to retard oxidation corrosion, epoxy resin was used as surface treatment, with gray and black colors. Bonded magnets have high dimensional accuracy, can be made into relatively complex magnetic components, and have the characteristics of one-time forming, multi-polar orientation, polarity moulding is very elastic.
 
What shapes can bonded NdFeB be made?
The shape of bonded Nd-Fe-B can be divided into tile (motor magnetic tile), cylinder, ring (ring magnet), abnormal bonded magnet and so on.
 
What are the magnetizing methods for bonding NdFeB?
The bonded Nd-Fe-B magnetization can be divided into thickness magnetization, radial multipole magnetization (external or internal), radiation charge (radiation ring), plane multipole charge, paired magnetization (tile magnet), oblique charge of radiation ring, etc.
 
What are the physical properties of bonded NdFeB?
Density of bonded NdFeB: 5.8-6.2g/cm 3
Curie temperature of bonded Nd-Fe-B: 310-340 C
Bonded NdFeB hardness: 80-120 Hv
Bonded Nd-Fe-B resistivity: 0.026_.cm
Compressive strength of bonded NdFeB: 3kgf/mn2
Compressive bending strength of bonded NdFeB: 25kg/mn
