Product : Bread Shape Magnet

Permanent magnets can be devided into four kinds as below: (1)AlNiCo magnets; (2)the first generation of magnets is SmCo5 which is called 1:5 Samarium Cobalt Alloy; (3)the second generation of magnets is Sm2Co17 which is called 2:17 Samarium Cobalt Alloy; (4)the third generation of magnets is NdFeB which is called Neodymium Iron Boron Alloy. With the development of science and technology, the performance of Nd-Fe-B permanent magnet have been continuously improved and its application fields are expanded. Sintered NdFeB with high magnetic energy products (50 megagauss ≈ 400kJ/m3), high coercive force (28EH\32EH) and high temperature coefficient (240C) have been mass produced.

Xinqi's advantage is precision magnets, for those tight tolerance, difficult shape, small size, high grade are what we experienced, we welcome our customer's inquiry.
