  • This table shows measurement data by Daido's standard test pieces and not guranteed values.
  • Moreover, since the above mentioned value is varied depending on magnet shape, its dimensions, test conditions and equipments. It is recommended that the figures would be certified in actual products.
  • The guarantee value would be consulted and set by the shape & size.
  • NITROQUENCH-P is SmFeN bonded magnet using resin as a binder. Heat causes the change in the material, physical & mechanical property and dimension. Please examine enough by actual conditions before use.
  • The contents of data may change without prior notice.
