  • Product Detail
  • Technical Specifications

Linkup Magnet manufactures sintered neodymium magnet in custom sizes upon requirements.Our machining capabilities provide perfect solutions for both regular shapes and special shapes of sintered neodymium magnet,with good quality and maintain the price advantage.

  Available dimensions of arc sintered neodymium magnet

Relying on experienced production team and strong maching capability,most sizes of neodymium magnet can be produced with very high quality,and the tolerance can be controlled within +/-0.05mm or +/-0.1mm.



Length Width Height Wall Thickness Angle
L ≦ 200 mm W ≦ 100 mm H ≦ 80 mm T ≦ 80 mm A ≦ 180°



  How to choose the grade of sintered neodymium magnet


Basis on different temperature resistrance, the neodymium magnet are divided into N, M, H, SH, UH, EH, AH series, and the corresponding maximum operating temperature is 80℃, 100℃, 120℃, 150℃, 180℃, 200℃, 220℃.

In the same serires, the higher the grade of NdFeB magnet, the more magnetism it is. For example, in N series,N52 grade have more magnetic power than N35 grade, and the N55 grade is the strongest one.

For initial projects, we are happy to provide magnetic technology support and accept sample order according to your requirements for prototyping and testing needs.
