SmCo Disc Magnets Material: Cobalt Samarium

Various Dimension such as D10x2,D2x2 ,D3x1.2,D1.5x1.5,D80x30 and so on can be done from SmCo5 magnets or Sm2CO17 Magnets.

Maximum diameter can up to 120mm, the Minimum Diameter is only 1mm.

Ucoated or Ni coating can be choiced.

Axially magnetized or diametrically magnetized available.

Feature

1.Smco5 Magnet are brittle and hard , are easy chip or break if dropped or stick each other.

2. Smco5 Magnet have high magnetic properties than AlNiCo and Ferrite Magnets

3.Smco5 Magnet offer better thermal stability than Ferrite magnets,Neodymium Magnets;

4. Smco5 Magnet is better resistant to corrosion than Neodymium Magnets;

5. Smco5 Magnet is good resistant to demagnetization than Ferrite magnets,Neodymium Magnets;
