Sintered NdFeB Magnets - Products - Advanced Technology & Materials Co., Ltd.

Advanced Technology &他生amp; Materials Co.,Ltd (AT&線日;M) has a long histo制從rical standing and is one of the worl能秒d leading manufacturer in R&D and p門離roduction of NdFeB magnets in China. A黑湖T&M was honored 老老with one state invention awards(the通中 third grade), two state a計議wards for science and technology advanc數愛ement (the first grade愛們 and the second grade), as w得就ell as 25 patents.

AT&M achieved the certificat腦山ion of ISO9001 in Nov 2003;女都 ISO14000&OHSAS18000 in Oct 20在制06; ISO/TS16949 in Aug 200鄉術7, held the manufacture 理河license and sold sintered NdFeB mag路技nets under SSMC (NEOMAX) p資術atents in 2003. Nowadays美土, AT&M has a prod畫從uction capacity of 4000 tons for N能暗dFeB magnets with middle or hig舊車her grade annually.

Description of Grades fo空習r the Sintered NdFeB M從離agnets:

· Nd-Fe-B magnet--------A身從TMAX＃＃XX

· ATMAX: The magnet pr請日oduced by AT&M Co.,L筆紅td.
&n影生bsp; ＃＃: The typical value of (BH)m.
&算好nbsp; X X: The typical value of intrinsic coercive force.

For example: ATMAX40湖裡H is a sintered NdFeB magnet with (B票那H)m of 38~41MGOe, and H睡綠cj≥17kOe.
