Sintered Nd-Fe-B magnets are the best choice for high-end commercial motors due to its high energy and shape variety. Since the Nd-Fe-B magnet is vulnerable to corrosion, it needs to be coated before use. A common coating protection for sintered Nd-Fe-B is NiCuNi.
Features
1.The Sintered NdFeB Magnet belongs to the rare earth alloy magnet group. It is made from Nd, Fe, B and other rare earth elements.
2.NdFeB Magnets offer the strongest magnetism with the highest energy product and coercive force.
3.These magnets are easily formed into a variety of shapes and sizes via the cutting, drilling, grinding and wire-cutting process. Popular shapes include discs, rings, squares, sectors and segment types. Shapes can also be custom-made.
4.As a high energy product, NdFeB Magnets can be designed for lightweight and thinner applications in electronic devices, mobile phones and micro motors. Green energy and automotive industries also play a large role in the current use case of NdFeB Magnets.
