| The introduces of NdFeB magnet
What area does the NdFeB applied in?
The neodymium ferrum boron permanent magnet is a saving energy material , it can produce constant magnetic fields behind specifically space. Because of whose very high brave stubborn strength and magnetic energy capability,excellence shown relative to other permanent magnet , feasible neodymium ferrum boron permanent magnetic materials has gained in especially modern various field high-tech area extensive use especially under 20 ~C ~ 180 ~C condition. Such as Electromotor , speaker , VCM sound circle motor etc. , generator , receiver , measurement instrument etc., magnetism parts for , magnetic suspension , magnetic drive , magnetism hang the magnetism acetabulum , magnetic resonance etc.

If the actual working temperature approaches the maximal Yu usage temperature, but the magnet has appeared comparatively by a wide margin demagnetize , to improve the magnetic loop magnetism lead modulus this moment or must improve; Must choose higher shop sign function grade or , ensure that the magnet regularity works thereby.
Which matters needing attention does · magnet operation have?
Neodymium iron boron material quality characteristic is hard but fragile , that the magnetizing queen attracts weight is above 600 times of oneself weight , the small side door extremely easy to suck knocks against. Operation process ought to pay attention to avoiding knocking against crippling to small specification , being going to pay attention to more to big specification is person's safety and protection. · neodymium iron boron function price
