Bonded NdFeB Magnet

Neodymium magnets (also known as “NdFeB”, “Neo” or “NIB” magnets), are strong permanent magnets made from an alloy of neodymium, iron & boron. Part of the Rare-Earth magnet family, they have the highest magnetic properties of all permanent magnets. Due to their high magnetic strength and relatively low-cost, they are the preferred choice for many consumers, commercial, industrial and technical applications.NdFeB is divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB is magnetic in all directions and corrosion resistance and is divided into Bonded Compression NdFeB Magnet and Bonded Injection NdFeB Magnet; while sintered NdFeB is easy to corrosion, the surface requires coating, generally divided into axial and radial magnetic charging.

Compression Bonded NdFeB Magnet:

Compression Bonded NdFeB Magnet is composed of a special form of NdFeB powder with adhesive and using compression molding techniques in simple tools, it can be quickly machined into complex shapes. Since its materials are isotropic, bonded NdFeB magnet can be magnetized in any directions or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple poles magnetization, depending on complexity of design and production.

➢ Advantages of Compression Bonded NdFeB Magnet:

1. Very hard and brittle, high diamagnetic resistance, high cost / performance ratio, not suitable for high working temperature;

2. Magnetic performance is higher than that of the rare earth cobalt permanent magnet, the residual magnetic induction strength, magnetic induction coercivity, the maximum magnetic energy product is very high, is the current magnetic performance of the best permanent magnet;

3. High-cost performance.

Injection Bonded NdFeB Magnet:

Injection Bonded NdFeB magnet is a kind of new generation composite material made from

permanent magnetic powder and plastic. Injection NdFeB powder is blended with a plastic material and injection molded. With High precision size, it can be made of complex shapes and also bonded with other components. The injection molding magnet can be magnetized in any directions with multiple poles.

➢ Advantages of Injection NdFeB Magnet:

1.Designing and manufacturing of orientation molds were carried out.

2.Haing high dimensional precision and impactresistance, capable of forming products with inlay.

3.The injection molding parts are suitable for forming products with various shapes and thin walls.

4.Multi polar magnetization can be carried out according to customers' requirement.
