What is NdFeB Magnet?

As the strongest permanent magnet in the world, sintered NdFeB (Neodymium Magnet) has excellent permanent magnetic properties and high cost performance compared with traditional permanent magnet materials. Magnets made of neodymium, iron, boron and other trace elements through powder metallurgy process.

 

Characteristics of NdfeB Magnet

(1)Excellent Magnetic Properties (High Remanence, High Coercivity, High Magnetic Energy Product, Low Reversible Temperature Coefficient, Low Weight Loss Characteristics);

(2)Excellent Machining Performance; 

(3)Poor Surface Oxidation and Corrosion Resistance, needs surface treatment/plating (such as Phosphate, NiCuNi, Zinc, Epoxy, etc.); 

(4)Hard and Brittle

 

Advantage of NdfeB Magnet

(1)Excellent Magnetic Properties (High Remanence, High Coercivity, High Magnetic Energy Product, Low Reversible Temperature Coefficient, Low Weight Loss Characteristics);

(2)Excellent Machining Performance

 

Disadvantage of NdfeB Magnet

(1)Poor Surface Oxidation and Corrosion Resistance, needs surface treatment/plating (such as Phosphate, NiCuNi, Zinc, Epoxy, etc.);

(2)Fragile

 

What Are the Applications of NdFeB Magnets

NdFeB Magnet is widely applied to Machinery, Video and Audio equipment, Communication Devices, Medical Devices, Office Automation Equipment, Space Flight and Aviation, etc. More than 95% of our products are applied in Industrial Automation, Automotive Industry, Clean Energy and other High-end Applications, especially in all kinds of energy-efficient permanent magnet motors, such as Elevator Motor, Servo Motor, New Energy Vehicles Drive Motor, Compressor Motor, High Speed Motor, Explosion-proof Motor, etc.

 

Grade of NdFeB Magnet

  • N30~N55
  • N30M~N52M
  • N30H~N52H
  • N30SH~N50SH
  • N25UH~N50UH
  • N28EH~N48EH
  • N28AH~N45AH

 

Price of NdFeB Magnet

Customized Products, price is determined by the Grade/Performance, Specification, Coating, Magnetization Direction, Quantity, Transportation, etc.

 

How to produce the NdFeB Magnet?

Process: Raw Materials Preparation→Strip Casting(SC)→Hydrogen Decrepitation(HD)→Jet Milling→Pressing→Vacuum Sintering→Magnetic Properties Inspection→Machining→(Grain Boundary Diffusion(GBD))→Surface Treatment(Coating)→Magnetizing and Inspection→Packing and Shipping
