The characteristics of the plastic magnetic ferrite and strong magnet

It is well known that some mold production without the use of magnetic ferrite, but a lot of people is not very understanding to it. Today is to introduce the characteristics of plastic magnetic ferrite, and to see strong magnet purposes and characteristics.
Plastic magnetic ferrite Curie temperature is 465 ℃, ferrite Curie temperature is 310 ℃, alnico ndfeb Curie temperature is 800 ℃, so the temperature stability of the ferrite, but the highest performance, known as "magnetic king". At present there are sintered and bonded magnetic material production of two kinds of process, the added adhesive binding due to the magnetic can not high, but high precision products. Ferrite permanent magnet material is based on intermetallic compounds Nd2Fe14B permanent magnetic material, high magnetic energy product and coercive force, high energy density at the same time, thereby plastic magnetic instruments and meters, electronic motor miniaturization, lightweight and magnetization of the magnetic separation equipment.
Strong magnet is called rare earth strong magnetic, it has the advantage of cobalt SanTie main, including magnetic strength, small volume, light weight, through the evaluation of the industry says it is one of the best cost-effective magnets, can be bold, estimates that in the next twenty years won't be able to completely replace the ferrite magnetic material. It includes a lot of production material, and also should pass strict proportion configuration, respectively, with metal, metal praseodymium, neodymium ferro boron and so on. Its core technology is mainly manifested in the manufacturing process, main is to ensure that products of uniform, consistent, and has high machining quality and coating quality. It quite widely application of industry, energy, transportation, machinery, etc., for the industry and related industries brought a broad space.
