The rare earth family is composed of 15 elements from the lanthanide series, plus 17 elements related to lanthanum and lanthanum. They are: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium , scandium, yttrium. This long list of element names looks boring. We just need to know. Among them, the largest user of metal ruthenium is NdFeB permanent magnet material. The advent of NdFeB permanent magnets has injected new vitality and vitality into the high-tech field of rare earths. The rare earth magnet with NdFeB magnet as the material has a high magnetic energy product and is called the contemporary "King of Permanent Magnets". It is widely used in electronics, machinery and other industries for its excellent performance, and it has derived reprocessed products such as rubber coated rare earth magnets
according to industrial needs.
The rubber coated rare earth magnets are formed by injection and calendering after the hard ferrite material is mixed with the polymer and adhered. Material characteristics: hardness bottom, good plasticity. Therefore, it can be easily processed into various shapes. It is widely used in toys, stationery, door seals, micro-motors and so on. Rare earth magnets
, which have high remanence, high coercivity and high magnetic energy, are widely used in the electronics and aerospace industries.
