Neodymium (NdFeB)
NdFeB, the third generation of rare-earth permanent magnet, has high remanence, high coercive force, high-energy product and high performance/cost ratio.
Neodymium Magnets are easily formed into various sizes and widely used in many fields such as magnets for aviation, electronics, instruments, meters, machine and medical instruments. Neodymium metal is used extensively to produce Nd-Fe-B magnets, which have energy densities as high as 27 to 35 million gauss oersteds.
They are the most compact magnets commercially available. It is especially suitable for the development of magnets for high-performance, compact and light products.
Bonded NdFeB Magnets
Bonded NdFeB magnet is made through "compression molding" or "injection molding" of the mixture of quick-quenched NdFeB magnetic powder and bonding agent.Due to its high accuracy in size, the bonded maget may be formed into magnetic components of relatively complicated shapes. Also,it features single-time molding and multi-pole orientation. The injection molded magnet has a high mechanical strength and may be molded together with other matching parts
One of the greatest advantages of the injection molding process is that a high degree of shape complexity is possible — ie. gears, snap fits and undercuts. It is also possible to incorporate shafts, bushes and other inserts into the process, simplifying the magnetic assembly manufacturing process
Physical Characteristics of bonded NdFeB Magnet
Bonded NdFeB is produced by a technique whereby a special form of NdFeB powder is blended with a plastic carrier material, die pressed aThey have lower energy products than Sintered NdFeB - in the range of 10 MGOe. The Bonded NdFeB materials are isotropic - i.e. they can be magnetized in any direction
We are specialized in manufacturing all kinds of bonded rare-earth permanent magnets, now mainly bonded NdFeB magnets as the leading products. According to the customers request, we can produce all kinds of NdFeB magnets with different complicated shapes and get them magnetized with multi-poles. The products are widely used in motor, micromotor, computer, instrument, car, motorcycle, amera, watch, HiFi, electric appliances, office automation, toy, magnetic therapy and other fields of daily life.
Bonded NdFeB Magnetsnd then heated. Parts made in this way can be of complex shapes and come off the tool with close tolerances, requiring no further finish machining.
