2-9795-05 Neodymium Magnet (Round, With Plate Hole) φ25 10 Pieces NR216


  • It is a molded and sintered product mainly consisting of neodymium, iron and boron.
  • Very good magnetic energy is the best existing magnet.
  • It has excellent mechanical strength with few cracks and chips.
  • Another advantage is that they are cheaper than Samakova magnets, which are also rare earth magnets.
  • It is also suitable for manufacturing shapes suited to applications by machining and for trial production in small quantities.
  • It has high magnetic properties, so even a small size can make a magnet with strong magnetic force.
  • We handle not only normal materials (N-40) but also strong neodymium (N-52, N-55) and heat-resistant neodymium (N-40SH).
  • The temperature characteristic is low, and for normal materials (N-40), the operating condition is less than 80°C. However, heat-resistant neodymium, which is used under 220°C, is also popular.
  • It is very easy to rust, so it is treated with nickel plating or other surface treatment.
  • Nickel plating, epoxy coating, nylon coating, fluoroplastic coating, galvanizing and gold plating can be used for surface treatment.


  • Residual magnetic flux density: 1.13 T (11,300 G) to 1.32 T (13,200 G)
  • Heat resistance: about 80 ° C
  • Surface treatment: nickel plating
  • Diameter × inner diameter × thickness (mm): φ 25 × φ7 × 4
  • standards : M6 plate
  • Quantity: 1 box (10 pieces)
  • Round and countersink
  • Model number: NR 216
  • * surface flux density is a reference value.
