Product Detail

DESCRIPTION

NdFeB is the highest commercialization of the magnet found, known as the magnetic king. NdFeB permanent magnet material is based on the intermetallic compound Nd2Fe14B permanent magnet material. Compared with casting Al-Ni-Co permanent magnet material and ferrite permanent magnet material, NdFeB has a very high magnetic energy product and coercive force, can absorb the weight corresponding to 640 times its own weight.

NdFeB magnet has the advantage of cost-effective, good mechanical properties, while regulating the chemical composition of the production process and to take the surface coating method to make the scope of application more widely.
