Those who magnesy neodymowe material composition

Second, by those who magnesy neodymowe material composition?

NdFeB magnets main raw materials are rare earth neodymium (Nd) 32%, metals iron (Fe) 64% non-metallic elements and boron (B) 1% (small amount of dysprosium (Dy), terbium (Tb), cobalt (Co), niobium (Nb), gallium (Ga), aluminum (Al), copper (Cu) and other elements). Magnesy neodymowe permanent magnet materials based on Nd2Fe14B ternary compound as the substrate, and its composition should be similar formula with a compound Nd2Fe14B. But when exactly Nd2Fe14B composition ratio, the magnets can be very low, or even non-magnetic. A magnet which is the actual content ratio of neodymium and boron compound Nd2Fe14B magnesy neodymowe and boron content is large in order to obtain better magnetic properties.

Third, the magnetic properties of magnesy neodymowe can last long?

NdFeB magnets have a very high coercivity, the natural environment and general conditions do not appear demagnetization magnetic field and the magnetic variation. Assuming proper environment, even after prolonged use, the magnets can damage will not be great. Therefore, in practical applications, we tend to ignore the time factor on the magnetic properties.

Four on the orientation direction

Orientation direction: get the best magnetic anisotropic magnesy neodymowe direction as the direction of magnetic orientation. Magnet divided into: 1, isotropic magnets: are the same in any direction of the magnet magnetic

2, anisotropic magnesy neodymowe: in different directions have different magnesy neodymowe properties;, and there is a direction that alignment direction is oriented in the direction of the resulting magnesy neodymowe highest magnets. Sintered NdFeB magnets are anisotropic, and thus need to determine the orientation direction of the pre-production (magnetization direction).
