Sintering NdFeb irregular magnets with its superior performance, rich raw material, the reasonable price are to rapid development and wide application. The main application in micro &special motor, permanent magnet instrument, the electronics industry, automobile industry, petroleum chemical industry, nuclear magnetic resonance (NMR) device, audio equipment, maglev system, magnetic transmission mechanism and magnetic therapy equipment, etc. Ndfeb magnets are easy to rust, oxidation, so the surface of ndfeb magnets usually requires plating processing, such as zinc, nickel, silver and gold, also can do the phosphorus treatment or gush to slow down the epoxy resin oxidation speed.

Key Advantages:
- Neodymium magnets are the most powerful commercially produced magnets.
- NdFeB magnets have a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes up to 50 MGOe.
- NdFeB magnets can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.
- Very high strength.
- Relatively low cost.
- Compared to Alnico and SmCo magnets, relatively easy to machine.
