Neodymium magnets are the most powerful rare earth magnets up to now and regarded as The King of permanent magnets. Nowadays, neodymium magnets are under a very fast development and wide application. It is getting to replace the traditional magnets such as ferrite magnets, alnico magnets, smco magnets in many fields. We can produce Neodymium magnets in various shapes, such as disc magnets, ring magnets, rectangle magnets, arc magnets, and some other special shaped magnets. We can also offer a variety of different coating suited to the environments of the neodymium magnets, such as nickel, zinc, epoxy, tin, chrome, silver, gold. At present, we can manufacture N52 Neodymium magnets. It is already closed to the top Neodymium magnets that made by Japan or USA.

Bonded NdFeB magnet includes compression moulding NdFeB magnet and injection moulding NdFeB magnet. Due to its high accuracy in size, the bonded NdFeB magnet may be formed into magnetic components of relatively complicated shapes. Also, it features single-time moulding and multi-pole orientation. The injection molded NdFeB magnet has a high mechanical strength and may be molded together with other matching parts.

Sintered NdFeB magnets are composed of Nd, Fe, B and other few minor elements. Sintered NdFeB is the most powerful rare earth magnet today processing high energy product and good coercive force.
Customers usually require sintered NdFeB magnet with coating, such as Zinc, or Nickel, or NiCuNi multi-layer, or Epoxy etc.

Because of high magnetic properties, Sintered NdFeB is widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware, machinery, aerospace and other areas, the more common are sintered NdFeB permanent magnet motors, speakers, magnetic separator, computer disk drives, MRI etc.

China Rare Earth Magnet Limited supply Neodymium magnets, sintered and bonded. Bonded neodymium magnets are generally low in properties due to the special process of gluing the powder in a mold. Although bonded neodymium magnets do not possess magnetic properties as advanced as those of sintered neodymium magnets, they can be made in shapes and sizes that are difficult to achieve with sintering. Neodymium magnets are brittle (though not as brittle as the SmCo types). All Neodymium magnets, except the bonded NdFeB magnets are anisotropic, and can only be magnetized in the orientation direction. Bonded NdFeB magnets is isotropic and can be magnetized in any direction, and with multiple poles, although special magnetizing fixtures are required for this.

New electric vehicle will set off the industry's rapid growth, and low carbon economy will make the global market of new energy vehicles and small lightweight cars bloom, which also drive the long-term demand for neodymium magnets materials. New energy vehicles will be the key target market of neodymium magnets; take Toyota Prius for example, the extra demand for neodymium magnets will up to 2000-3000 tons if we take one million newly increased cars into account. The development of wind electric motor also becomes an important supporting point for rare earth permanent magnets. Another focus which pulls the demand of rare earth permanent magnets is frequency appliance industry.
