Among those famous d25x5mm round magnets and super magnets in the magnetic materials manufacturers, it is a professional supplier in China, welcome to wholesale d25x5mm round magnets and super magnets in the magnetic materials from our factory.D25x5mm Round magnets and super magnets in the magnetic materials   Neodymium disc magnets (Nd-Fe-B) are made from the most powerful magnetic materials in the world. These supper magnets have superb strength for their size. Supper magnets are composed of neodymium, iron, boron and a few transition metals. Strongest magnet has many advantages like high coercive force, high energy, high performance/ cost ratio and can be easily formed into various shapes and widely used in many fields such as aviation, electronics, instruments, meters, DC motors, Liner motors, MRI, medical and health products. Strongest magnet is the third generation of rare earth permanent magnet and at the same time the most powerful and advanced commercialized permanent magnet today. Following regular size of D25x5mm round magnets are popular in many applications.SpecificationSizeD25x5mm round   magnetsTolerance +/- 0,1 mmDirection of   magnetisation Axial Magnetic Materials   NdFeB (Neodymium   Iron Boron)Coating  Ni-Cu-Ni Strength approx. 6 kg   approx. 58,8 NWeight 11,938 gGradeN42Max. working   temperature 80°CResidual   magnetism Br 12900-13200 G   1.29-1.32 TCoercive field   strength bHc 10.8-12.0 kOe   860-955 kA/mCoercive field   strength iHc ≥12 kOe ≥955 kA/mEnergy product   (BxH)max 40-42 MGOe   318-334 kJ/m3   Feature· HK/Hcj>97%  · Flux density consistency>98%  · Nickel coating>72 hoursDemagnetisation curve N42 Magnetic field strength versus magnet-encoder distance for D25x5mm round magnetsPacking Video For Reference For more magnetic materials, super magnets,round magnets, strongest magnet,please visit :/GreatMagtech/?ref=aymt_homepage_panel
