Neodymium Iron Boron Magnet

High-Performance Magnetic Rod Separator for Industrial Applications

Magnetic rod separators are essential components in industrial filtration systems, designed to efficiently remove ferromagnetic contaminants from various materials, ensuring product purity and equipment protection. Our magnetic rod separator is engineered with high-intensity rare-earth magnets and advanced sealing technology, making it an ideal choice for industries such as food processing, pharmaceuticals, chemicals, and mining.

The rod features a high-density magnetic circuit composed of premium NdFeB magnets and a conductive sheet, ensuring superior magnetic performance. Sealed in a stainless steel tube through argon arc welding and polished to a mirror finish, the magnetic rod offers exceptional resistance to corrosion, wear, and contamination.

Permanentmagnet Neodymium Iron Boron Magnets

Neodymium Iron Boron (NdFeB) Magnets are the world’s strongest permanent magnet because it provides superior permanent magnetic qualities and high-cost performance, unlike traditional magnets. They are widely used in the manufacturing of industrial, medical equipment, home appliances, energy, and transportation-related products. With many years of design and R&D experience, Dailymag has dedicated itself to the development and manufacturing of high coercive force, low reversible temperature coefficient, and low weight loss NdFeB. It features high-performance consistency and excellent quality. We can provide customers with customized neodymium iron boron magnets and solutions.

Surface Coatings for Neodymium Iron Boron Magnets

NdFeB magnets with nickel, zinc, or tin plating have good corrosion resistance, although longer lead times or higher volumes may be necessary. Ion vacuum deposition (IVD) techniques can also be used to plate neodymium magnets. This particular plating offers exceptional adherence to the material and is very controllable in thickness.

A number of organic coatings with good corrosion resistance have also been successfully produced for NdFeB. In particularly harsh settings, a combination of coating processes or encapsulating the material in a sealed housing may be preferable.

APPLICATIONS

Permanentmagnet neodymium iron boron magnets are widely used in machinery, video and audio equipment, telecommunication technologies, medical devices, office automation systems, spacecraft and aviation, and many more applications. More than 95% of our products are used in energy-efficient PM motors, particularly Servo Motors, New Energy Vehicles Drive Motors, Compressor Motors, Elevator Motors, High-Speed Motors, Explosion-proof Motors, and so on.

Bonded NdFeB Magnet

Sintered NdFeB magnets are difficult to process into special shapes, and they are easy to crack, break, and difficult to assemble during the process. In order to solve these problems, people tried to crush the permanent magnets and mix them with adhesives, and then press them into a shape in a magnetic field. Thus, the bonded NdFeB magnet was developed. It has the advantages of low cost, high dimensional accuracy, a large degree of freedom of shape, good mechanical strength, light specific gravity, etc., and has been widely used in the market. There are currently 4 processes for forming bonded neodymium magnets: calendering, injection molding, extrusion, and compression molding, of which calendering and injection are more mainstream. Bonded NdFeB magnets are generally only 80% of theoretical density due to the addition of a large amount of adhesive, so they are weaker than sintered NdFeB magnets in terms of magnetic properties. Bonded NdFeB magnets are isotropic magnets, with the same magnetism in all directions, so they are convenient to manufacture multi-pole monolithic magnets. (Bonded NdFeB magnets can also be made into anisotropic magnets)

Conclusion

The three types of neodymium magnets have their advantages. Due to the huge difference in magnetic properties and molding, the intersection between bonded NdFeB magnets and sintered NdFeB magnets is not large. Bonded NdFeB magnets are mainly used in fields such as hard disk drive spindle motors and low-power micro-special motors, while sintered NdFeB magnets are more used in fields such as high-power drive motors. The hot-pressed NdFeB magnets are only used in automobile EPS due to the limitation of shape.
