Block Shape NdFeB Magnets are widely used in auto motors,computers(disc drives),communication,speakers,medical equipment,wind generator,magnetic resonance image and other field.

Product Details

Rare earth permanent magnet NdFeB is the strongest permanent magnet in contemporary magnets. Its BHmax value is 5-12 times that of a ferrite magnet, 3-10 times that of an alnico magnet; its coercive force is equivalent to 5-10 times that of a ferrite magnet, and 5-15 times that of an alnico magnet. Its potential magnetic properties are extremely high, and it can absorb heavy objects equivalent to 640 times its own weight.

Since the main raw material iron of NdFeB magnets is very cheap, the storage of rare earth lanthanum is 10-16 times more than that of samarium-boron magnets, so the price is much lower than that of samarium-cobalt magnets.

NdFeB magnets have better mechanical properties than samarium cobalt magnets and AlNiCo magnets, making them easier to cut and drill and complex shape processing.

The insufficiency of NdFeB magnets is their poor temperature performance. The magnetic loss is high at high temperatures and the maximum operating temperature is low. It is usually around 80 degrees Celsius. In specially treated magnets, the maximum operating temperature is up to 200 degrees Celsius.

Because the material contains a lot of bismuth and iron, it is also a major weakness of rust. Therefore, the neodymium iron boron magnet must be surface coated. Electroless nickel (Ni), zinc (Zn), gold (Au), chromium (Cr), epoxy (Epoxy) and the like.

NdFeB magnets are widely used in industrial aerospace, electronics, electromechanical, instrumentation, medical and other fields. Moreover, non-technical fields are becoming more and more widely used, such as adsorption magnets, toys, jewelry, and the like.
