  • sintered neodymium magnet

Neodymium permanent magnet material available in the early 1980s, is now widely used in motor (motor), speakers (speaker), toys (toys) and some electrical appliances (electron), and other products. Components for Nd2Fe14B. Have very high magnetic properties, the largest energy product (BHmax) higher than the ferrite (Ferrite) 10 times more. Its own mechanical properties is also very good, cutting different shapes and bored. High-performance products of the highest temperature of up to 200 degrees Celsius. Because of its material content easily lead to corrosion, according to different requirements of different surface coating. (Such as plating Zn, Ni, Au, Epoxy, etc.)
 
1. Materials: Neodymium-Iron-Boron;
 
2. Technology: Utilizes new Sintered NdFeB magnet techniques and equipment such as strip casting, HDDR technology; 
 
3. Magnetic properties: High coercive force, the max operation temp is up to 200 degree centigrade or 380 curie temperature; 
 
4. Grades: N33-N52,33M-48M,33H-48H,30SH-45SH,30UH-38UH and 30EH-38EH;
 
5. Shapes and Sizes: Various kinds or according to customers' request;
 
6. Coatings: Ni, Zn, gold, copper, epoxy, chemical, parylene and so on;
 
7.Applications: Widely used in different applications, such as sensors, motors, rotors, wind turbines/wind generators, loudspeakers, magnetic hooks, magnetic holder, filters automobiles and so on.
