NdFeB Magnets
- Sintered NdFeB: N33 - 52 (M,H,SH,UH,EH,AH)
- Bonded NdFeB: BNM 5 - 12

NdFeB is the strongest type of permanent magnet commercially available.
- Higher remanence (the strength of the magnetic field);
- Higher coercivity (resistance to being demagnetized);
- Higher energy product (density of magnetic energy);
We are able to custom the shape and coating for your specific requirements

General Introduction |
Neodymium magnet (NdFeB), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron. Two kinds of Neodymium, Sintered NdFeB and Bonded NdFeB, are commercial according to their different manufacturing process. |
Features |
NdFeB is the strongest type of permanent magnet commercially available.Higher remanence (the strength of the magnetic field), coercivity (resistance to being demagnetized), and energy product (density of magnetic energy) than other type magnets, however often lower curie temperature. |
Typical Grades |
Sintered NdFeB: N33 - 52 (M,H,SH,UH,EH,AH) Bonded NdFeB: BNM 5 - 12 |
Property |
Some important properties used to compare permanent magnets are:

Shape |
Neodymium magnets could be made into various shapes:
Custom design is available to us for client`s specific needs |
Coating |
NdFeB tends to be vulnerable to corrosion, which could cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles, or spalling of a surface layer. Coating prevents these magnets from oxidation. Widely used coatings are NiCuNi, Ni, Zn, Epoxy, as well as some special coatings, for example, Copper, Gold, Silver, and etc. |
Application |
Neodymium magnets have replaced Alnico and Ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:

Production |
Sintered NdFeB: Raw Materials → Melting → Pulverizing → Aligning & Pressing → Sintering → Annealing → Machining → Surface Treating → Magnetizing → Inspecting → Packing & Delivery Bonded NdFeB: Rapidly quenched NdFeB Powder → Particle size adjustment → Kneading with other material → Molding → Secondary Process, Surface Treating, Grinding → Inspecting → Packing & Delivery |
